Magnetization Measurements On Gadolinium In The Temperature Range 4.2 To O 300°k
Abstract
'vfa,gncti7.ntion. neasurenents of spherdcal samples of both
single crvs tal and polycrys tal Hne r.adolinium are presented.
Measure1rents '..rcre mm1e as r functd on of both temperature and
magnetic fi e Id; high field measurements were J"IAne us ing a. Foner
vibrational magnetore te r and J ~·t ficlc reasurenents Here made using
a SQ.JID (Superconducting Quantum Interforencr- ne",'i ce ) magnetCJUeter
,·.•hich is based on the' Jo~eph..~on effect. The temperature range was
between 4.ZoK and 3CXPK. From the nhove measurements th
following are calculated:
~) the vnrinti0n of directicn of c~sy magnetization with
temperature in Gadolinit.•m.
b) th rnagnctccrystnllinc anisotropy constants of
Cadolini\tm es a functdon of temperature.
c) the temperature van ation of the saturation moment
'.,
in Gadolinium.
d)
the Curie temperature, Te' of Gadolinium.
