Abstract
Mössbauer spectroscopy and magnetization measurements were carried out on Fe-RE multilayers where RE=Nd, Tm. Perpendicular and in-plane anisotropy direction for Nd-Fe and Tm-Fe multilayers was respectively observed. The atomic structure was studied by Mössbauer spectroscopy, small angle X ray scattering and transmission electron microscopy. The structure of the layers is built from pure iron and pure neodynium sandwiching a NdFe paracrystalline interface layer. We demonstrate that multilayer structure can be used to give a choosen magnetic anisotropy.
