By applying Monte Carlo simulations in the canonical ensemble, investigation of the magnetic properties of Fe/Cu multilayers is carried out in comparison with Mössbauer experimental results. From differing relaxation rates for spins with few near-neighbor spins and particularly those located at the interface, the Mössbauer result can be simulated. Our model consists of an alternate stacking of iron and copper layers (Fe n Fe /Cu n Cu ) with disordered interface. The simulation results confirm that the concentration of interface alloys (Fe 1− x Cu x ), measurement temperature and magnetic layer thickness modify systemically the magnetization distribution in the Fe/Cu multilayers. The result is compared with Mössbauer experimental analysis. Meaningful results are obtained by analysing the dynamical microscopic behaviour of individual spins.
