摘要：

The experimental magnetic phase diagram for three characteristic Fe/Gd multilayered samples is confirmed on a microscopic scale by Fe-57 Mossbauer spectroscopy using a special geometry. The iron moment rotation in the sample plane at a critical H* external field is observed and signals the transition from an aligned to a twisted state. This behavior is accounted for within the framework of an improved mean-field model. Self-consistent spin maps are derived for given temperatures and external fields applied parallel to the sample plane. A unique set of exchange coupling constants is used to calculate both the mean magnetic properties and the Mossbauer spectroscopy data.
