Abstract: | A Monte Carlo Simulation (MCS) has been used to study critical behavior and magnetic properties of a decorated Ising film on a cubic lattice structure. The system consists of two magnetic atoms species A and B with and , where the B sites decorate the bonds between A sites. The dependence of the phase diagram on the axial zero-field splitting parameter, the exchange interactions and the thickness of the film are studied. We found that the system exhibits a double reentrant phenomenon and one or two compensation points. MCS results are compared to those obtained by using the effective field theory (EFT) based on the use of a probability distribution technique. However, MCS predicts the same topology of the phase diagrams as the effective field theory. |
