Using nuclear resonant scattering of synchrotron radiation and density functional theory calculations we have resolved the magnetic properties of the different Fe phases present at the Fe/NiO(001) interface, an epitaxial ferromagnetic/antiferromagnetic system. We have detected the presence of an interfacial antiferromagnetic FeO-like phase with a significantly increased magnetic moment compared to the case of a sharp interface. Already a few atomic layers above the interface, the Fe atoms have a bulk-like metallic character and the reversal of their magnetization is strongly influenced by the antiferromagnetic layer.

Abstract

Using nuclear resonant scattering of synchrotron radiation and density functional theory calculations we have resolved the magnetic properties of the different Fe phases present at the Fe/NiO(001) interface, an epitaxial ferromagnetic/antiferromagnetic system. We have detected the presence of an interfacial antiferromagnetic FeO-like phase with a significantly increased magnetic moment compared to the case of a sharp interface. Already a few atomic layers above the interface, the Fe atoms have a bulk-like metallic character and the reversal of their magnetization is strongly influenced by the antiferromagnetic layer.
