Magnetic Properties and Phase Diagrams of a Spin-3/2 Blume–Capel Multilayer System

The magnetic properties, phase diagrams, and hysteresis behavior of a spin-3/2 Blume–Capel multilayer system are studied using the Monte Carlo Simulation. First, we have established the ground-state phase diagrams for T = 0 K. Then, we have plotted the thermal variations of the two sublattices and total magnetizations, as well as the corresponding phase diagrams in order to investigate the effects of some Hamiltonian parameters, namely the exchange interactions, the crystal field, and the number of layers. Finally, we have analyzed the hysteresis behavior where there is the formation of one or three loops. This study shows the appearance of a certain number of features, especially the existence of second- and first-order phase transition border lines and critical isolated end points.
