Monte Carlo Study of the Interface Effects on the Magnetic Properties of the Magnetic/Nonmagnetic (M/NM) Layers

A Monte Carlo study of the thermal variation of multilayers magnetization is carried out. We find a number of characteristics behaviors of the interface magnetization with its roughness. The spontaneous magnetization and magnetic susceptibility are calculated. It is found that multilayers magnetization decreases and phase transition temperature from ferromagnetic to paramagnetic varies with increasing interface thickness and concentration of nonmagnetic atoms in interface. Moreover, the susceptibility exhibits peaks at the transition temperature and it is interface morphology dependent. The dependence to the spin-exchange coupling is reported.
