'Oroblem in the region of transitions from the paramagnetic to the antiferromagnetic
phase and vice versa of the rare earth metals Dy and Er for which the magnetic

and Hall amf in DY and Er are measured in the temperature range from 4.2-to 3500X-
The transition from paramagnetic to antiferromagnatic phase can easily be discerned
on the ?(T) curves for Dy and Er. An investigation of the vpocific Hall emf for
Dy :revealed that extramal values of the effect correspond to transitions from a.

tra sition from the antiferrom-agnatic to the ferromagnetic phase. The Dy Hall
-effect in the farrornsgnetic and anti flerroma onetic region exhibits "hysterosis" and
changes its.sign from negative to positive at tomperstures between 100 anti 1500K.
The sign.of the Hall effect in Er is negative through the whole investigated

...:ABSTRACT: A substance is said to possess unidirectional anisotropy (UA) when its
magnetic properties differ In the two directions of the same crystallographic axis.*
This phenomenon was first observed by W.H.Mejklejohn and C.P.Bean (PhYS.ReV. 105,
.904,1956), who ascribed Its appearance in their material to an exchanga interaction
across the bowidaries between ferromagnetic and antiferromagnotic phases. Two of
the present authors have suggested that UA could appear in a single ferromagnetic
substance provided a weakly interacting sub-lattice constituting an antiforrcimagne-;
tic subsystem.were presoixt, and they have given a thermodynamic.4liecussion of a unit_

'axial system of this sort (K.D.Vlasov and A.I.Alitack, Fizilca metallov i metallove-
:deniye,14,487,498,1962). In the present paper the theoretical treatment is extended,
;to systems with cubic symmetry. UA is pobsible when the coupling between the anti-
Iferromagnetic vector and the crystal lattice is stronger than the coupling between
..Ithq'ferromagnetic and antiferromagnetic subsystems. The states with UA are meta
stable and can be altered by application of a magnetic field exceeding the thresh-
,old field of the antiferromagnetic subsystem. UA was observed in disordered Ni-Mn
.:alloys (28.1 atomic percent Mn) at temperatures below 20.40K. The magnetization was!
:investigated in the [111) direction, and the UA was evinced by a characteristic berdi
'in the magnetization curve or by a horizontal shift of the hysteresis loop. Samples,
!that were cooled in the presence of a magnetic field showed UA; those thit were
1cooled in the zero field did not. The samples were subjected to an interuie pulsed*
magnetic -f ield (up to 170 kOe) ir, an ef f ort. to alter their UA. At 4.2oK a f ield of
1
10 kOe appreciably altered the UA of a sample that had been cooled in a field of `
i
11300 Oe, and a field of 130 kOe changed its sign. A sample that was cooled in the

.absence of a magnetic field and initially showed*no UA, acquired UA when subjected
~,to magnetic fields greater than 60 kOe. The degree of UA (as measured by the shift
:of the hysteresis loop) was a linear function of the field for inducing fields
greater than 60 kOe. These fields are of the order of the threshold fields for typi-

to normal state is abrupt in the absence of the magnetic field and increasingly smooth

the disruption of superconductivity occurs over a wide range of the values of the
current and magnetic field. Apparently, various sectors of the superconducting cir-
cuit differ in the dependence of their critical current an the intensity of the mag-
netic field. Electric resistance increases with increasing magnetic-field intensity.
On the whole, the character of the transition curves indicates that, in the alloy
investigated, disruption of superconductivity by current in a longitudinal magnetic
field occurs gradually owing to the successive elimination of the superconducting
state of individual sectors of the superconducting circuit. Although specimens in
fields of the order of 20 kilo-oersteds become markedly heated, some of their sectors
still remain in superconducting state. "The authors are indebted to A. Prekul for
affording them the opportunity of performing the measurements with the aid of a super-
conducting solenoid." Orig. art. has: 3 figures.

ABSTRACT: To obtain additional information on the ijagnetic anisot( -earth

metals, the authors investigated the Hall effect in single-crystallhamples of gado-
li~~ium (p(2q2K)/p(4.2K) ='.20) in the temperature interval 4.2 - 370K. The measure-
ments were made with cryst4s cut in two jautually perpendicular directions. In the
fir$t the primary current was directed along the ao axis and the magnetic field along
the-co axis, and the Hall field was measured in the b0 direction. For-the second
sample the primary current was along eto, the magnetic field along bo, and the Hall
fie4# along co. The authors have published elsewhere the procedure used to measure
the,-_1ktll emf (FMM v. 2, 377, 1956) and the data reduction procedure (FM4 v. 18, 26,

SOURCE: Fizika tverdogo tela, v. 8, no. 6, 1966, 1895-1898
TOPIC TAGS: holmium, Hall effect, temperature dependence, rare earth metal
ABSTRACT: In view of the lack of data on the temperature dependence of' the Hall ef&C'
in holmium, the authors measured it in the interval 4.2 - 300K. The holmium purity' Vas
99.9% (030OK/p4.2K = 12) - The inductions used in the sample reached 20 kG. The pro-
cedure used for the measurements was the same as in an earlier paper (1,M4 v. 2, 377,
1956). The data-reduction procedure was also described elsewhere (FM v. 18, 26, 1963)1.
The dependence of the specific Hall emf on the induction for different temperatures
and on the temperature for different inductions are plotted, and the effective Hall
coefficient is calculated. The temperature dependence of the specific Hall emf ex-
hibits a minimum at 100C, and the Hall coefficient consists of two components, the
ordinary one, vhich does not depend on the temperature (found to be -2..8 x 10-3-2
ohm-cm/G), and a component inversely proportional to the temperature, which includes
the anomalous Hall coefficient connected with the paramagnetic magneti:z'Mon. The
latter is likewise independent of the temperature and is found to be 42.2 x 10- 3-2
ohm-cm/G. The results are compared with those obtained for dysprosium and erbium,

x-ray studies down to liquid nitrogen temperatures revealed no static lattice do-
formation~. The specimen was cooled through the 1110 K transition temperature in an
external magnetic field parallel to [ioo] and the measurements were riade with the
field in that direction. The spontaneous magnetization M(T) at temperature T was

ABSTRACT: The purpose of the investigation was to ascertain the effect of a change
in thq. magnetic structure on the anisotropy of the transverse magnetoresi,;tance of
single-crystal gadolinium in a wide range of temperatures. The tests were made orr
cylindrical samples cut along -the (1010) axis, with a ratio of room-temperature
resistance to helium-temperature'resistance equal to '220. The Isotherms of the trans-
-verse magnetoresistance were measured in fields sufficient to produce sat,uration and
extrapolated to zero field in the sample, so as to exclude the resistance variations
due to the paraprocess. Thetests showed that the transverse saturation magnetore-
sistance has a complicated temperature dependence and is strongly anisotropic. From
the measured temperature dependence of the transverse saturation magnetoresistance in
fields parallel to (0001] and (11~03 it is deduced that the magnetic anisotropy can-

250K the transverse magnetoresistance is negative in all directions, and its absolute
value is minimal in the easy-magnetization direction. Below 130K, the rotation curves
show maxima connected with the appearance of the "cone" of easy magnetization axes.
The results show also that a correlation exists between the terq)erature de.Tendence of

ABSTRACT: Data are given from measurements of the Hall effect in neodymium and
samarium of N99.9% purit at temperatures from 2.4 to 3500K. The Hall. effect in
Nd is positive throughouti-lhis lCemperature interval. The specific Hall emf is a
linear function of induction In- the-Nd specimen above 20.410K. Curves for e ft (B)
have a poorly defined inflection at 20.40K which shows up more clearly when the
temperature is reduced. The e H(B) curves for 4.2 and 2.410K show two Linflections:
one at Iv6-7 kilogauss corresponding to the critical range of the magnotic field
which destroys antiferromagnetism, and a second at lulS-20 kilagause due to fez'L

magnetic saturation. The Hall emf in Nd is only slightly dependent an temperature
in the 100-3000K range. There is a noticeable inflection at n6O-700K although no
change is observed in the magnetic structure of the specimen. As the temperature
approaches the Ndel point, eH increases sharply and then diminishes at lower tem-
res. However, the maximum e is not at the Ndel point but at 7-00K, 1. e,,
,peratu H
at the temperature for interchange of magnetic planes. The Hall effect is nega-
tive at high temperatures in Sm, changing sign at -1700K. Contrary to other lan-
thanons, the Hall effect in Sm is considerably dependent on temperature in the
paramagnetic region. Hall emf in this element is a linear function of induction
with only a slight inflection in the eR(B) curve at 4.20K. The maximun effective
Hall coefficient in Sm is reached at a temperature of -'uVOK, i.e., somewhat higher
than the Ndel point. These results are compared with the field and temperature re-'
lationships of the Hall effect in the heavy lanthanons. It is concluded that the
field and temperature singularities with respect to the Hall effect in lanthanons
is due to the unusual magnetic structure of these elements. Recommendation is made
for a study of anisotropy in the Hall effect in lanthanon single crystals. Orig.

ABSTRACT: To elucidate the magnetic properties of Eu304 the authors measured tile
temperature dependence of magnetization in the presence of different maSuatizing
fields at temperatures of upward of 1.65*K and thus determined for the first time
the principal magnetic characteristict of EU304: saturation. magneLi--atioa Cr. and
Curie,temreratura TC. The mcasurements were perfermed with the aid of a peAulu'M

to be 89.4 gauss-cm3/g. From the same curves, using the Weits-Forrer method of
lines of equal magnetization, the authors found the Curie temperature, which
proved to be 7.8*K. With its relatively large magnetic moment and-low Curie point,
this oxide appears a suitable means of verifying the spin-waive theory. Verifi-
cation of this theory showed that the linear TZ-depandence of saturation magneti-
zation, exists throughout a broad temperature range (from 1.65 to 4.6*9) (0.6 TC ).
The same dependence is also observed for a number of uncompensated antiferromag-
netics and for certain rare earths. Orig. art. has: I figure.

ABSTRACT: The authors point out that it would be desirable to measure the electri-
cal conductivity and the Hall coefficient on the same pure samples of all the rare
earths over a wide temperature range (down to liquid helium temperatures) under uni-
form conditions, and they assert that they have done this. ZAbstracter's note: No
,experimental details are given, nor any description of the techniques employed-7
;The interest in measurements of this sort arises from the fact that, al,,;hough the
rare earths all have the same valence electron structure, the electric and galvano-
magnetic properties vary greatly from one to another. Some of the results of the

Imeasurements are discussed in the present paper. With respect to tomperature depen-,
'dence of resistivity, the rare earths divide themselves into two groups. In La,Ce,
!Pr,Nd and Yb there is no region in which the resistivity is a linear function of
,~temperature. The curve for Nd is given; it is smooth and concave to the temperature
axis. In Sm,Gd,Tb.,Dy,Ho,Er and Tu the resistivity depends linearly on temperature
throughout the paramagnetic region, and :he curve has a sharp bend at the paramag-
netic-antiferromagnetic transition point. The behavior of Eu (curve given) is very
peculiar: there is no linear region (up to 3000K), and the peculiarity at the tran-
Isition point is very marked, there being even a small region in which the resistivi-
ty decreases with increasing temperature. This behavior is tentatively ascribed to
ichanges in the conditions of scattering and in the energy spectrum of the current
Icarriers. The Hall emf in all the rare earths is proportional to the induction
throughout the paramagnetic and antiferromagnetic regions. In sozae of the metals
~the current carriers are holes, and in others they are electrons. The number of car-
mriers per atom varies widely, from 0.17 (holes) In Eu to 3.6 (electron.;) in Lu. The
behavior of the Hall emf in the ferromagaetic region is very complex. Orig.art.has:

Original Periodical: Tr. Leningr. tekhnolog. in-ta imeDi 4'1ensoveta, 1955, 32, 32-41.
Abstract: A method is proposed for measuring the heat characteristics of solid and
liquid bodies having a wide range of heat conductivity and temperat:xre conductivity.
All the thermal characteri st ics are found simultaneously in a single experiment and
the measurements;, as well as the processing of the e-xperimental results, take I-Ittle
time. The method proposed consists of placing a plane-parallel plate A of thickness
R of the material under investigation (or a plane layer of liquid) between a heater,
the temperattLrre th of which remains constant during the entire time of the eyperi-
menT. and a standard medium B, the temperature characteristics of which are lmovn.
The initial t,-mperatura of both media A and B is the same. If one of the junctions
of a thermocouple is located in medium B sufficiently far away from the heater, and

Abstract: of the standard mediumJ, and the quantities Z2 and 6 are taken from tables
or from graphs, obtained by solving the heat conduction equation, giving the d;---
pendence of Z2 and E on the ratio-E2/c, obtained as a result of the experiment at
definite values of ki and k2. A check on the method, carried out vith rubber and
distilled waterhas sh--,-wm good agreement with the results obtained by other methods.
