Magnetic Properties and Hysteresis Loops of the Mixed Spin-1/2 and Spin-3/2 Blume Capel Model on a Multilayer Square Lattice

Abstract

This paper is a study of a multilayer system with mixed spins S = 1/2 and spin S = 3/2 by the Blume Capel model using Monte Carlo simulation. The phase diagrams (at T = 0 and T ≠ 0) as well as the total magnetization have been determined. The critical temperatures have been deduced from the different values of the system parameters, namely the exchange interactions JB, the crystal field ∆ and the numbers of layers of the system NA and NB. It became apparent that the system presents both the first and second-order transitions. In addition, we see the appearance of one of the serval phenomena which is compensation behavior. Moreover, the hysteresis behavior present single and multiples hysteresis loops for well-determined values. Finally, our results are compared with the other theoretical and experimental works.
