In this paper we study the magnetic bearing of a bilayer film in anisotropic extended Heisenberg model, using the Monte Carlo method. In this way, by computing the out-of-plane uniform and staggered magnetization, in-plane uniform magnetization, out-of-plane and in-plane magnetic susceptibility, we point out the existence of an antiferromagnetic phase induced in the superior layer as a consequence of the fixed ferromagnetic arrangement of the spins in the base layer. We can also distinguish the existence of two phase transitions which occur in the physical system: antiferromagnetism → mixed phase transition and antiferromagnetism → XY-like phase transition, corresponding to the two physical parameter settings.
