摘要
Depth-dependent Fe spin structures of the remanent state in exchange-coupled Fe/MnF2 films have been probed using Fe-57 conversion electron Mossbauer spectroscopy, both above and well below the MnF2 Neel temperature. Fe-57 probe layers were embedded either at the Fe/MnF2 interface or in the center of the Fe film. Remarkably, exchange bias induces a significant change of the in-plane angular distribution of the Fe magnetic moments at the interface and inside the Fe film, away from the saturation magnetization direction. Results from vector magnetometry support these conclusions.
