Abstract

We report on the thermal effects on a two-sublattice system in the mean field approximation using computer simulation. In particular we study the temperature dependence of magnetization, magnetic susceptibility, and magnetic heat capacity for a system in which the magnetic state is determined by the magnetic anisotropies of the two components of the compound and the exchange interaction energy between them. The partition function is first determined, subsequently the magnetic properties are derived from the partition function. In certain cases, the findings of the model are compared with experimental data on rare-earth transition metal alloy system.
