Structural and magnetic properties of Ni/gamma-Fe/Ni multilayers

The crucial point in the characterization of magnetic interfaces is the knowledge of the morphology and the structure of the films. Ni/gamma-Fe/Ni multilayers were grown on three different buffer layers. Structure and morphology were investigated by X-ray diffraction and scanning tunneling microscope. Mossbauer spectroscopy was used to provide local information on both structure and magnetism of the buried Fe layers.
