Fe/Dy multilayers exhibit interesting magnetic properties depending on the interface nature (roughness and interface diffusion). In particular, they may exhibit a perpendicular magnetic anisotropy which is correlated to the existence of an Fe-Dy alloy at the interface. The aim of this work is to investigate the magnetic properties of amorphous Fe/Dy multilayers by Monte Carlo simulations for different concentration profiles. Our model is based on a face centered cubic lattice where each node is a classical Heisenberg spin. We have considered an anisotropy modelbased on a small concentration of uniaxial easy axis (in average), the other have a random easy axis. We evidence an inhomogeneous magnetisation profile related to the concentration p...
