In the last years, the study of the antiferromagnetic-ferromagnetic interfaces was a very exciting topic in the thin film area. Using the Monte Carlo technique (by applying the standard Metropolis algorithm) and the extended Heisenberg model with low dipolar interaction, the influence of the antiferromagnetic base layer on the magnetic properties of the multilayer thin film is investigated, in the ferromagnetic region of the phase diagram of the system. For each ferromagnetic layer individually, we study the physical quantities of interest (assuming particular physical conditions): the out-of-plane magnetization, the magnetic susceptibility and the specific heat and we point out the Ising-like ordering of the magnetic spins. The obtained numerical results show that the critical temperature of the individual layers decreases as we approach the base antiferromagnetic layer and consequently, the stability of the ferromagnetic phase increases with the distance from the base layer.
