Abstract
Depth-dependent Fe spin structures of the remanent state in exchange-coupled Fe/ films have been probed using conversion electron Mössbauer spectroscopy, both above and well below the Néel temperature. probe layers were embedded either at the Fe/ 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.
