pulse comparison. The process of synchronization is explained, and formulas
describing zones of synchronization are developed. Two experimental circuits
designed along the above lines were tested with these results: (1) An electron-
tube circuit ensured a maximum division ratio of SO-70, with a supply-voltage
Variation of t 20% and a synchronizing -pulse frequency of 75 kc; (2) A
transistorized'circuit exhibited a maximum division ratio of 40, with the same

TITLE: Investigation of Ferrites in the Vicinity of the
Curie-Puint (Issledovaniye namagnichiVaniya ferritov v oblasti
tochki Kyuri)
PERIODICAL: Izvestiya AN SSSR, Seriya Fizicheskaya, 1957, Vol. 21, Nr 8,
pp. 1047 - 1054 (USSR)
ABSTRACT: The paper under consideration deals with the magnetization pro-
cesses of some ferrites in order to determine the temperature
change on spontaneous magnetization near to the Curie point. It
is maintained here, that such data are missing in literature,
although they are of great importance, because the mech&nism of
ferromagnetic phenomena in ferrites are different from ferromag-
netic metals. The sections of the paper are headed:
1.) Samples and methods: 7 samples of Mn-Zn ferrites with a
-
varying MnO content T
20 -. 40 ~) and 2 ferrites of Co-Zn alloy
were selected. The measuring of the magnetization curves was
executed according to the ballistic method. The samples were
mar.,-netized in a solenoid with a field strength of 2500 Oe. A
Card 1/3 ballistic differential winding, consisting of two sections of

4500 spires each on an ebonite body, was mounted on the electric
furnace containing the sample. Forcalibration a one-layer wind-
in- of thin wire was prepared, which was wound on a body of the
identical form and size as the sample. By introducing- this wind-
ing ins tead of the sample calibration was effected. 2.) The
curves of actual magnetization of ferrites near the Curie point:
Here it is established, that in this case the well-known thermo
dynamical equation 2 H
Ot- + P a- _67 is applicabb, Er denoting
the specific magnetization and thermodynamical coeffi
cients. The conclusion is drawn, that the sequence of the values
of the para-processes of ferrites under investigation corresponds
to the sequence of ferromagnetic metals. The theoretic relation
between the intensity of the paraprocess and the value of the
Curie point is stated here as follows: The lower the Curie point,
the weaker is the interaction and the higher the effect of the
excitation of the external field, implying a higher intensity of
the paraproceS3es. 3.) The reaction of Un-Zn ferrites ih weak
fields near to the Curie point: Here the magnetic anomalies are
deocribed, of which allegedly no data are to be found in litera-
Card 2/3 ture. These data consist of the fact, that the final magnetiza-

tionpf the above-mentioned Mn-Zn ferrites, starting from low
temperatures, first dearoaaes at the approach of the Curie point,
startsto grow just before reaching the Curie point, and finally
falls off after reaching a certain maximum. The coercive force
behaves similarly, which, in some cases, shows a very accentuated
rise from the minimum to the maximum. These anomalies can be re-
produced also, if the samples are isolated from the influence
of air. No anomalies of this kind were found in Co-Zn ferriteB.

TITLE: On Magnetic Properties of Ferrites Exhibiting a Compensation

ABSTRACT: In the present paper the authors performed exact measure-
ments of the magnetic properties of mixed lithium chromite
ferrites (which were annealed and hardened) in the case of
different annealing after hardening. For the investigation
a system of ferromagnetic lithium spineis that contained
chromium of the common formula
Li 20-0 - 2a) Fe 203 ' 2 a Cr203 (for a = 1,25; 1,5; 1,6; 1,7)
was synthetized. The following magnetic characteristics
were investigated: 1) Temperature dependence of the spontan-
eous magnetization of a (T); 2) magnetic moments of the atoms
(the measurements were garried out by A. V. Ped1ko);

the limiting cycle in the temperature range of from -30 0 to
about 10to .200above the compensation point (by the astatic
maCnetometer); 4) temperature dependence of the paramagnetic
sensitivity (according to the ponderomotive method). The
measuring results showed that the ferromagnetic spinels
Li FeCr in a certain range of solution exhibit an anomalous
shape of the curve as (T) with a compensation point. This
has been predicted by Neel. In contrast to the theory it
was found that the compensation never was perfect. The
phenomenon of an imperfect compensation may be explained by
the heterogeneity of the samples. An other considerably
greater difference is that the value of the absolute satura-
tion computed (according to Neel) from the distribution of
the cations does not agree at all with data found experimentally
(Table 2, column 3 and 5). The modification of Neel's
theory suggested by Yafet and Kittel (Ref 6) is capable of
explaining this discrepancy qualitatively. The explanation
is as follows: As the measured value of the magnetic value
in these ferrites is lower than the value computed according

interaction within the sublattice B compared with the inter-
action between the sublattices A and B must not be neglected.
The measurements showed that the value of the absolute
saturation in the system LiFeCr-ferrites becomes higher
in the case of hardening. In technical publications there
are data on the influence of hardening upon 6 0 of various
simple and composed ferrites (Refs 10 and 11) and theories
(Refs 12 - 14) explaining the results of the papers (Refs
10 and 11). According to this C 0 depends on the distribu-
tion of the cations on A and B . This distribution, however
depends on the temperature. In the present case the problem
became more complicated as apart from the cation distribu-
tion also the variation of the angles between the magnetic
moments in sublattices was possible. The possible influence
of these two factors excludes a comparison of the experimental
values found of saturation in hardening with respective
theories. The question of the influence of these factors
probably might be answered by means of radiographic and
especially neutronographic investigations. The authors

ABSTRACT: Ferromagnetic spinels of the composition L12O(5 - 2a)Fe 20 3* 2aCr 203
with 1.!G~d:!52 have the characteristic property that their sponta-
neous magnetization changes to zero not only at Curie temperature
but also at lower temperatures. This temperature is called
compensation point in which an equilibrium of magnetic moments
of the sublattice may be observed. Experiments carried out by
the authors (Ref 3 ) showed that an anomalous change of the coercive
force of these ferrites is found in the temperature range of the
compensation point and of Curie temperature. The authors give two
reasons for the fact that u alight
be aoderts.ined at compensation point: i) 81i&ht fluctuations in
the chemical composition. 2) Heterogeneous cation, distribution in

about of spontaneous magnetization leads to the conclusion that the
coercive force increases with increasing approach of the temperature
to compensation point, reaching a maximum at this point. To check
this assumption, the authors carried out experiments to determine
the temperature dependence of coarcive force, of spontaneous
magnetization, and of remanent magnetization. In all compositions
and heat treatments it was shown that the coercive force passes a
distinct maximum in the range of ,'.he compensation point which seems
to confirm the original assumption of an anomalous temperature
course of the coercive force in the range of the compensation point.
An analysis of the data obtained (which are to clarify the causes
of the anomalous behavior of coercive force) shows that with the
approach of temperature to the COMDensation point the magnetization
curve flattens more and more, which suggests an increasing influence
of the rotary mechanism on the maFnetization of ferrites. Table 2
shows that in hardened ferrites the difference between Curie and
compensation temperature becomes smaller, which suggests that
hardened ferrites have a lower anisotropic constant than annealed
ferrites. There are 5 figures, 2 tables and 6 references, 4 of which

ABSTRACT; Ferro-magnetic spinels, the composition of which is
described by the formula Li20 x (5-2a)Fe2O3 x 2aCr2O3,
in the range of a =.1 to a = 2, are characterized by the
fact that their spontaneous inognatization is reduced to
zero not only at the Curie temperature but also at a
lower temperature at the so-called compensation point
(Ref 1 and 2). The authors have carried out a thorough
experimental investigation of the temperature course of
spontaneous magnetization of the above materials in the
compensation and Cunietemperature range (Ref 3). An
analysis of these results has led to the conclusion that
an increase in Mc of these ferrites must occur in the
compensation range Tk1 which is associated with a sharp
decrease in magnetization as the testing temperature
approached Tk' The figure on p 462 shows the temperature

Magnetic viscosity which appears between 1 and 250 oe was measured in
static magnetic fields between +20 and -200 0C, In some cases magnetic
viscosity exerted a strong effect upon magnetic reversal- Though field
direction was changed, the ferrite remained magnetized for se-eral hours
in the former direction. This effect, up to now unknown, was found to be
particularly strong in a certain low-temperature range as well as in weak
and medium magnetic fields. Specimen no. 4 displayed the greatest delay
of magnetic reversal, Por no- 1 and no- 3 viscosity was lower and

appeared also in weaker fields. In such fields.. a-c hysteresis loops
(50 cps) were recorded by an oscilloscope. No loop forms in weak fields
in which magnetic reversal takes a long timed With increasing field
strength a perminvar loop appeared first, followed by a normal and
finally by a rectangular loop. The loop shape was chan in this way if
the specimen is demagnetized at room temperature, Whengris reversed at
measured temperatures the oblique line changes in a jump-like manner to a
distinct rectangular loop (Ir/Is- 0.98), with increasing field strengths
An abrupt rise of induction, forming a step in the loop, is observed if the
field strength is increased in the temperature range beTween -"00 C and
-150OCi where viscosity is partioularly high, The saturation magnet-o-
striction in a 2500 0e field was measured by means of pickupe glued onto
them. The effect of viscosity upon magnetostriction was noticeable only
in specimens no. 2 and no, 4~ Magnetoatriction depended largely oil the
method of demagnetization. As for specimens no, I and no~ 3 (without
cobalt), viscosity was lower, and the degree of magnetostriction did not
depend on the method of demagnetization. For the ferrites examined~ it
was found that a connection must exist between the hysteresis and
magnetostriction properties and magnetic viscosity. One and the same

mechanism is probably responsl'ole for all these properties, Uniaxial
anisotropy, which was discovered in these ferrites is probably due to
electron diffusion: Ion diffusion is little Drobable at such low tempera-
tures, The finite diffusion rate deDends on temperature and on the
magnetic field strength. This explains the limitation of the temperature
and field ranges in which the described phenomena are observed- The part
played by cobalt has not been clarified, The unclear statement contained
in the literature regarding the relationship between the perminvar effect
and relaxation according to Richter was substantiated by establishing a
direct relationship between the viscosity properties of the examined
ferrites in static fields and their hysteresis Droperties in the same

same ferrite, the saturation magnetostriction was measured at 2500 oel
as a consequence of the high viscosity, magnetostriciion was found to
depend strongly on the method of demagnetization of the specime-. The
hysteresis loops were also recoi.Aed by an oscilloscope in alternating
fields of 50 cps. Rectangular perminvar loops were obtained in this
range. A comparison of the change of the loop shape in growing alter-
nating fielils with the magnetic viscosity in static fields shows that
the character of the shape modification is closely related to the mag-
netic viscosity in static fields. If the time of magnetic reversal is
very long, the hysteresis loop will have the form oil a line; if it is
short (which is the case with certain fields and temperatures; e. g.,
at -1250C and 43 oe), that is less than one minute. a perminvar loop is
then obtained. This can be explained by considering that the ferrite
concerned causes in each domain an uniaxial anisotropy under the effect
of the magnetic field (with an ax4- -f slight magnetization in direction
of the vector of magnetization of the domain concerned). The appearance
of uniaxial anisotroD is due to electrop diffusion. 1.1ost like;- an

ABSTRACT: Magnetic lag was investigated at temperatures from -900C to -1600C in
ferrites having the compositions MnI.BrOl.204 and Unl.75CO0.05Fel.204- Both single
crystals and polycrystalline material wore investigated. Curves of magnetization
versus time were obtained at various temperatures and for various values of the
magnetizing field. Relaxation times from 0.5 min to a day were observed. Activation
.energies were calculated from the temperature dependence of the relaxation times'
corresponding to 75% and 95% saturation. The activation ener&7 for the material coa-
taining cobalt was 0.32 eV, and for the material without cobalt, 0.23 eV. MagZati-

zation curves corresponding to various stages of magnetic annealing (from 0.5 min
to 270 min) were obtained. From the magnetization curve obtained at the bogirminCs
of the anneal, Anti the oquilibrium magnotithtioij cujvo (Infillito Anneal) t the limit-
ing value of the induced uniaxial anisotropy constant Ku was calculated. Ku was
strongly temperature dependent, having a maximum at about -1350C. The maximum value
.of Ku was about 9000 erg/cm43 for the material containing cobalt, and only 66 erg
~cm-3 for the material without cobalt. The fall of Ku at temperatures above -1350C
:is easily understood in terms of L.Neel's theory of directed local order (J.Appl.
iVhys.30,SuP*pl.No.4,3S,l959). The decrease at lower temperatures is ascribed to in-,.
:crease of the cubic anisotropy constant. The constant W in the expression C
:cos2;U for the interaction energy of the cation with the spontaneous magnetization
(CC is the angle between tile trigonal axis and the spontaneous magnetizatiun) was
to?
calculated from KU = C GIC, where c is the concentration of cobalt. It was found
to be 10-15 erg/atom. In view of the work of S.Iida (J.Phys.Soc.Japan 17,Xo.1,123,
1962) and A.Braginski and T.Merceron (J.Phys.Soo.Japan No.10,-1611, 1962), the be-
havior of thematerial containing cobalt is ascribed mainly to ionic diffusion of
C02+. The behavior of the material not containing cobalt is ascribed to electron
diffusion by electron exchange among the Mn ions of different valence on the 16 d
sites. Orig.art.has: 3 formulas and 3 figures.

ABSTRACT: On the basis of systematic data reduction certain observati were made
concerning radio-signal fluctuations from Soviet artificial satellites7 These
fluctuations have a "twinkling" nature and have been recorded on all Soviet satellites
put in orbit during 1958--1962. It is postulated that these fluctuations can be
explained satisfactorily by relating them to diffraction of radio waves on ionospheric
inhomogeneities. The frequency of these fluctuations is shown to depend on the
latitude position of the satellite as well as the time of the day. A definite connec-
tion'was also established between the "twinkling" and the scattering phenomenon from
F-layer reflections. A careful study of cosmic particle bursts indicates some connec-
tion between the prevalence of radio-signal fluctuations and cosmic particle flux (in
bursts). It is postulated that these sudden fluxes give rise to ionospheric

ABSTRACT: This Author's Certificate introduces: 1. A multicormand active control.de-i
vice for regulating the feed on a grinder. The device contains a gauge assembly, a
comparator connected to a reference voltage unit, and an activating relay system. Mea
surement time is reduced and electric command adjustment is provided by making the
comparator in the form of a generator which sends out a control pulse when the gauge
signal and the reference voltage are equal. 2. A modification of this device in
which a filter is connected between the generator-comparator and the activating relay
system to reduce interference.

ABSTIUCT: 1) The authors investiCated the adsorpt-ion of low 'boiling
fractions of benzene solutions of normal hydrocarbons on urea.
These normal hydrocarbons were isolated from commercial
paraffins. The obtained experimental data are reproduced by
the Langmuir isothermal adsorption curve. The adsorption
coefficients and the limiting value3 of the adsorption
increase with increasing mean molecular weight of the fractions.
2) The isothermal adsorption curves on urea were investigated
for a number of commercial paraffins, but also for paraffins,
which were obtained from solutions of isoparaffins in benzene,
toluene, and carbon tetrachloride by purification, On that
occasion the concentration of the paraffine was kept constant,
while urea was added in increasing quantities (up to 12 U on

The isothermal curves of the commercial paraffins, on the

TITLE: Some Possibilities of Using Speed-Indicating Relay
Type RKS (0 nekotorykh vozmozhnostyakh primeneniya rele

PERIODICAL:Vestnik elektropromyshlennosti, 1959, Nr 6, p 65 (USSR)
ABSTRACT: Induction relay type RKS is used for speed indication
and control in the range 900 to 3000 rpm. The rotor of
the relay is coupled to the shaft of the motor to be
controlled; the stator of the relay is free to rotate a
littler so as to operate contacts as shown in the figure.
Rotation of the magnetised rotor sets up a torque in the
stator which is proportional to the rotor speed. As the
stator turns an arm presses on contact springs opening
a normally-closed contact and closing a normally-open
one. A feature of the relay is that the contacts are
not continually opening and closing because the normally-
closed contact opens an appreciable time before the
normally-opened contact closes. Thus there is a range of
speed in which the moving contact is either in the
neutral zone or is firmly over one way or the other. The
Card 1/2 relay is adjusted by altering the tension of the springs.

SOV/110-59-6-15/24
Some Possibilities of Using Speed-Indicating Relay Type RKS
Tests showed that the relay operates over the speed
range of 100 to 475 rpm. At a speed somewhere between
450 and 500 rpm, the normally-opened contact of the
relay is firmly closed. Thus at speeds above 500 rpm
the relay can only indicate that the motor is running
but cannot measure its speed. Test results are
tabulated for relays regulated for three speeds of
160v 225 and 450 rpm. It will be seen that the operation
of the relay is unreliable within a speed range of
50 to 80 rpm. To avoid the transmission of multiple
signals.at low speeds it is advisable to use in the
signalling circuit a relay with a delay time of between
1.5 and 2 sec. There is 1 figure and 1 table.

their concentration). This determination can be conducted automatically in

TEXT; In a previous paper (Ref. 1), the.first-mentioned author has-shown
that the adsorption of atoms and radicals on the surface of oxide-semi-
conductor films, e.g., n-type ZnO, causes a change of the conductivity of
the semiconductor. The present paper quantitatively investigated the re-
lationship between the radical concentration and the ZnO conductivity. By
means of a nPK-2 (PRK-2) lamp, acetone vapor was photolyzed in a quartz
cell having a mobile quartz frame, onto which the ZnO film (thickness about
5 p) 'was applied. The partial pressure of acetone vapor amounted to 0.1 -
100 mm F1g, the pressure of the inert gas (He, Ne, Ye) to I - 200 mm. Hg-
Temperature was 200 - 300 0C. The distance between ZnO and the aperture,
through which the photolytically generated CH 3. rad icals entered, could be
varied between 1-15 am by means of the mobile fraM6. The difference

Aa = a0 - a was measured (ao = initial conductivity). a = conBt/-p J3) was
obtained for a as a function of radical concentration n, a = const/ VI"(5)
as a function of the intensity I of the light absorbed. In Fig. 2 the vali-
dity of equation (5) is experimentally confirmed. When the partial pressure
of acetone was constant, ZnO conductivity linearly increased with increas-
ing pressure of neon. On the strength of these results the authors draw
the conclusions that recombination processes and the reactivity of radicals
and other free particles of various gases can be investigated by means of
this method. Different alcohol radicals have different effects on the
conductivity of the semioonduator, so that they can be identified in very
low concentrations by means of the method described. The authors thank
Professor S. Ya. Pshezhetskiy for discussions. There are 4 figures and
7 references: 2 Soviet, 4 US, and 1 German.
