TEXT; The study of the magnetic properties of the rare
earth~metalz is of interest inasmuch as the magnetic effects of
the
electrons lin the 4f-shell are well screened by external
electrons
from the.influence of other atoms. Previous
investig~ttions-have been
limited mainly to the low temperature
region. This paper describes the
results of an investigation of"
the temperature dependence of the
magnet~lc ounceptibility of the
polycrystalline metals Ho, Dy, Tb and
Gd in the temperature
range 300-1500 OK. The metali were 99.5% pure
and their magnetic
susceptibility was measured in an apparatus based
on the
~araday-Sixsmith method. The apparatus was calibrated by means
of electrolytic Ni and a NI-Al alloy (5 wt.% Al) for which the

data are well known. It in shown that the metal Ho follows the
Curie-Weiss law over the whole t',emperature range iuve~tigated.
This agrees with the results of other authors. From this are
obtained values for the Curie temperature (88 OK) and the
effective magnetic moment (Pj = 1o.6 In the case of Dy
there is a slight deviation from the Curie-Weiss law at
temperatures over goo OC. Its Curie temperature is 148 OK.
Gd, which is ferromagnetic, is studied near to its Curie
temperature'(17 OC) and it in found that there is no transition
region at the ferromagnetic transformAtion point. Gd obeys the
Curie-Weiss law for temperatures between 300 and 650 OK. Of the
metals investigated only Ho followed the Curie-Weiss law over
the whole temperature range 300-1300 OK; the others deviated at
h:Lgh temperatures. This may be qualitatively explained by the
theory of Van-Fleck which suggests -that the magnetle
susceptibility has two components, one of which in temperature-
dependent and the. other, a high frequency term, which is not.

TEXT: The temperature dependence of the paramagnetic susceptibility

Fe-Ni alloys was measured at T>Qf (of - ferromagnetic Curie point)

Ni. Special attention was paid to the y-phase of these alloys. The
susceptibility measurementa were made in the range 300-15000K by the
Faraday-Sucksmith method in an argon atmosphere. The curves 11X, -
f(T)
of the specimens with 27, 29, and 30. Va show a step which is
indicative
of an ar,?y transition. The 2V alloy has the highest step (at 82&K).
k of the 34-9 and 38.8% alloys satisfies the Curie-Wei8 law in the
whole
temperature range (no phase transition). Of the lower alloyed
specimens
only the y-phase was investigated; 1/7L - f(T) is a straight line.
Also
the magnetic moments P and the paramagnetic Curie points 9 of the

y-phases were measured, depending on the Ni-content. PP of
alloys with
more than 500/16 Ni decreases linearly with increasing
Ni-content. OP is a
non-linear function of the Ni-content. It has a broad maximum at
about
601jl~ Ni; in the range 30-4Vt'o it decreases rapidly, and at
20% Ni it changes
its sign, i.e. the y-phase of the alloys with less than 20i". Ni
and also
the phase of iron have a negative paramagnetic Curie point. This
is due
to the fact that, because of the negative exchange interaction
between
the iron atoms in the y-phase, the number of antiparallel spins
increases.
By extrapolating to pure iron, F P - 7-4 and Op a -30000K is
obtained.
This agiees with the Sucksmith-Pearce results (Proo. Roy. Boo.
A167P 189,
1938). 'The result that,in the I-phase at 4 2011 Ni, negati,/e
exchange
interaction occurs is in agreement with the theory of Ye. I.
Kondorskiy.

law X = C/(T - go was obeyed by all the samples. If the paramagnetic
Curie point 0 Is
determined from the experimental data, and the effective atomic
magnetic moment R is then
calculated, it Is found that these values change in proportion to the
praseodymium, 4t;nt.
The magnetic moments correspond to the magnetic moment of Pt+ ion,

Curie point 9 Is positive in Pr 41 Pr2 Se3, and PrSe7s and negative
in PrSe and 13rSe.; this

ABSTRACT: The authors present.the results of an investigation of~the,

X-ray structural analysis) revealed that the -homogenized- alloys form
monophase
systems, while alloys subjected to additional annealing are two-phase.

from 77 to'

the susceptibility,of the hoviogenized alloys varies smootbly
thr3ughout the range
of concentrations. For pure vanadium it is maximal (4,10-0 g-cm- ),
and it de-
creases with increasing Ta contentuntil, in the case.of pure Ta, it
drops to
0.95.10-6 9. -3
cm . At different temperatures,_ throughout the entire temperature
range investigated,-for.homogenized alloys, the temperature dependence
of.specific
susceptibility 1/X is linear (Fig. 2). The slope of the curved, which
is nearly
independent of alloy composition, indicates a certain localization of
d-electrons
in the alloys,investigated. The imost interesting results were
obtained-for alloys
containing 34 at.% Ta (curves 6, 7).Thus while the susceptibility of a
specimen
subjected to a single heat-treatment operation varies markedly with
temperatures
the susceptibility of the compound TaV2 Is nearly independent of T
(curve 7). This
indicates that, in this compound, the principal part of the
d-ele.6trons undergoes
a considerable collectivization, forming together with a-electrons a
common elec-
tron system. It is this electron system that largely determines the
magnetic
properties of the compound TaV2- It may :be assumed that thio'compound
is an.
CF-phasev whichl' as is known, exists in many vanadium alloys and
is-by nature an
electron compoundo Furthermore, these findings confirm the phase

ABSTRACT: The article presents the results of an experimental
investigation of magnetic
properties of Dy-Y alloys throughout the range of concentrafions
in the temperature interval of
from 100 to 1000% in the presence of magnetic fields of various
intensity. To this end, 9 alloys
of this system, containing 5.7, 11.9, 18.7, 26.6, 35, 44.1, 55.8,
68 and 83 at.% Dy (with '~f
as the remainder) were obtained by multiple remelting in a
helium-aftnosphere are furnace
and vacuum annealing at 10-6 mm Hg for 70 hr at 850*C. Magnetic
susceptibility was measured,
pe-
by the conventional ponderomotive method on using a magnetic
balance. Heating to high tem
ratures was accomplished with the aid of a platinum resistance
furnace, and the temperature

thermocouples. The
quartz cup containingthe specimen and the thermocouple junction
were in a uniform, tempera-
ture field. The magnetic balance was calibrated in advance with
