Abstract

In order to provide a structural basis for the modelling of the electronic and magnetic properties of the Fe/NiO(001) interface we haveperformed polarization dependent Fe K-edge X-ray absorption measurements. A multi-shell fit of the data is presented and discussed.We find that a 2 ML Fe film exhibits a complete tetragonal distortion of the unit cell and demonstrate the formation of a planar FeOlayer with expanded Fe–O distances perpendicular to the growth plane. We discuss a model for the interface with the FeO layer at theoxide–metal interface. At 10 ML thickness the tetragonal strain of the Fe film is partially released._ 2005 Elsevier B.V.
