Magnetic moment measurements on a series of Tb1-xNdxCd pseudobinary al
loys have been carried out from helium temperatures to room temperatur
es and in magnetic fields up to 1.4 MA/m. The Curie temperatures are o
bserved to initially increase as Nd is substituted for Tb, with a maxi
mum at x congruent to 0.25, Ferromagnetic coupling of the Tb - Nd spin
s results in antiparallel Tb (heavy rare earth) and Nd (light rare ear
th) magnetic moments throughout the series, with magnetization cancell
ation at x congruent to 0.75. Sharp maxima in the magnetizations at te
mperatures below their respective Curie points are interpreted as mark
ing magnetization reorientation temperatures.
