摘要：

The magnetic hyperfine fields near the interfaces in Fe/M (M = Cr, Gd, Y) layered structures were analyzed with monolayer resolution by means of Fe-57 conversion electron Mossbauer spectroscopy (CEMS). It was found that the range of magnetic Fe-Cr interaction extends only up to the second Fe neighbor at the Fe/Cr interface. In contrast, at the Fe/Gd interface the interaction range is four times larger. This is explained by a polarization of the Fe conduction electrons by the large Gd 4f moment. By inserting a spacer layer of Y between the Fe and Gd films an oscillating modification of the Fe hyperfine field was observed in dependence of the Y layer thickness.
