Magnetic moment measurements on a series of Tb/sub 1-x/Nd/sub x/Cd pseudobinary alloys have been carried out from helium temperatures to room temperatures and in magnetic fields up to 1.4 MA/m. The Curie temperatures are observed to initially increase as Nd is substituted for Tb, with a maximum at x/spl cong/0.25. Ferromagnetic coupling of the Tb-Nd spins results in antiparallel Tb (heavy rare earth) and Nd (light rare earth) magnetic moments throughout the series, with magnetization cancellation at x/spl cong/0.75. Sharp maxima in the magnetizations at temperatures below their respective Curie points are interpreted as marking magnetization reorientation temperatures.
