Reentrant Ferrimagnetism in A square Ising lattice

Abstract

Amixed spin Ising model SA=3/2 and SB=5/2 of a square lattice is investigated using mean-field approximation (MFA). In this study the influence of temperature on the magnetic moments of a mixed spin system is included. Besides that we have studied a reentrant behavior of the system which is considered for various values of anisotropies. It is found that a reentrant ferrimagnetism phenomenon in the system depends strongly on the anisotropy of the mixture.
