Study of a Nano-Square Structure with Defects: Monte Carlo Study
Abstract
In this paper, we study the defects effect on magnetic properties of a nano-square structure. This system is composed with alternate layers consisting of the spins {\sigma}=3/2 and S=1. More precisely, we examine the effect of different physical parameters which are: the coupling exchange interactions, the external magnetic and the crystal fields applied on the studied system. The ground state phase diagrams have been deduced and discussed in different planes involving such different parameters. Also we study the behavior of this nano-structure by using the Monte Carlo simulations. The behavior of the magnetizations is studied as a function of the external magnetic field, the crystal field, the temperature and the exchange coupling interactions. The magnetizations and the hysteresis cycles are presented and discussed for fixed values of these parameters.
