The paramagnetic susceptibility of Y--2-at.%-Dy, Y--25-at.%-Dy, Y--50- at.%-Dy, and Y--2-at.%-Ho solid-solution single crystals have been measured between 100 and 360 K. In the alloys with Dy, the anisotropy of the reciprocal susceptibility increases only very slowly with the concentration. This may mean that bilinear exchange anisotropy is small. The thermal variation of the second- order one-ion anisotropy parameter u$sup 0$$sub 2$/subz/ is in agreement with the screened point-charge model. When evaluated at sufficiently high temperature, the variation of u$sup 0$$sub 2$/subz/ from one rare earth to another is found to be close to that corresponding to this model. (AIP)
