Abstract
The magnetic susceptibility of polycrystalline cubic solid solutions of with , and have been measured. The of in increases with decreasing concentration of ions, although the anisotropic exchange interaction would be expected to decrease at the same time. The of the smaller unit-cell compound, , yields an even higher value for the of than do the Eu-Y mixed oxides, indicating a strong dependence of the crystal-field parameters on the unit-cell dimension. In the of has the same value as in for all values of while the of is given by .
