'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.
