Mössbauer effect measurements on 57 Fe have been carried out in the pseudobinary systems Er x Y 1− x Fe 2 and Tb x Y 1− x Fe 2 at 4.2, 80 , and 300 K. The isotropic part of the hyperfine field acting on the iron nuclei includes a term due to polarization by the localized rare‐earth spin. Magnetic dipolar contributions account only in part for the differences in the magnitude of the hyperfine fields at the inequivalent sites.
