Abstract

The Monte Carlo (MC) simulation is used to study the magnetic properties of a spin-1/2 Ising antiferromagnetic film sandwiches between two ferromagnetic surfaces. The influence of different exchange surface interactions on the phase diagram of such a film is studied. In the ordered phase, it is found that the antiferromagnetic layer of the film can change in ferromagnetic or ferrimagnetic phases, depending on the values of the surface, the perpendicular and the bulk magnetic couplings. Moreover, the sublattice magnetizations are computed as a function of temperature for a film of thickness n=10 and fixed values of magnetic couplings.
