Phase diagrams and compensation behaviors of a mixed Spin-(3/2,1) Ising-Type Ferrimagnet: Monte Carlo investigation

In this study, we perform Monte Carlo simulations to study the magnetic properties of a mixed Ising model on a cubic lattice where spins S-i(A) = 1 and sigma(B)(J) = 3/2 are located in sublattice A and B, respectively. The proposed Hamiltonian includes coupling to nearest-neighbors interactions, next-nearest-neighbors interactions, crystal fields D-S and D-sigma and external magnetic field h. We perform exact ground-state calculations for our model. The obtained results show the behavior of the critical temperature with the presence of the compensation temperatures under a certain range of parameters. Particularly, we found that the existence of compensation temperatures depends on the strength of the coupling to the next nearest neighbors between the S-i(A) spins and between the sigma(B)(J) spins, and it appears in a certain range of values of the external magnetic and crystal field of different spins.
