N2 - Depth-dependent Fe spin structures of the remanent state in exchange-coupled Fe/MnF2 films have been probed using 57Fe conversion electron Mössbauer spectroscopy, both above and well below the MnF2 Néel temperature. 57Fe 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.
