Hysteresis properties of a mixed ferromagnetic-ferrimagnetic ternary alloy

Abstract

In this work, we have investigated the hysteresis properties of a mixed ferro-ferrimagnetic ternary alloy system by Monte Carlo simulation method. The ternary alloy system contains two interpenetrating sublattices. One of the sublattice consists of type-A magnetic components with spin-3/2 while the other one is randomly occupied type-B and type-C magnetic components with spin-1 and spin-5/2, respectively. We consider both ferromagnetic and antiferromagnetic exchange interactions between nearest-neighbor magnetic components. The influences of the exchange interaction ratio, R, and the concentration value of type-B magnetic ions, p, on the remanent magnetization, coercivity and hysteresis loops of the system have been investigated in detail. It has been demonstrated that it is possible to modify the remanent magnetization, coercivity and also the saturation magnetization of the system by changing the concentration value and exchange interaction ratio.
