Abstract
The effect of a nonmagnetic impurity on the magnetization of its nearest neighbors is calculated in the random-phase approximation for a face-centered-cubic Heisenberg ferromagnet with first- and second-nearest-neighbor exchange. This is believed to be a good model for the behavior of Sn impurities in EuS.Keywords
