MAGNETIC-PROPERTIES OF TB1-XNDXCD

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.
