Mean-Field and Monte Carlo Study of a Mixed Ferro-Ferrimagnetic Ternary Alloy

Abstract

We present a study of the magnetic properties of a mixed ferro-ferrimagnetic ternary alloy of the type AB p C 1-p on a cubic lattice consisting of three different Ising spins S A = 3 2 , S B = 2, and S C = 5 2 . We employ the meanfield approximation and Monte Carlo simulation to find the compensation temperatures of the system for selected values of the parameters in the model Hamiltonian. In particular, the relation between considered mixed ferroferrimagnetic model and magnetic properties of the ternary metal Prussian blue analog such as (Fe II p Mn II 1-p )1.5[Cr III (CN)6] nH2O is discussed.
