✦ Synopsis

The magnetic properties of a decorated two-sublattice ferrimagnetic Ising model consisting of two magnetic atoms A and B with spins SA (SA = ½) and SB (SB > ½) are investigated within the framework of the effective-field theory with correlations. The uniaxial crystal-field interaction D exists on the B atoms and the effects of SB and D on the magnetic properties are examined. We find a number of characteristic phenomena in these quantities, such as the possibility of two compensation points and the two (or three) transition temperatures, not predicted in the Neel theory.

We give a precise numerical solution for decorated Ising models on the simple cubic lattice which show ferromagnetism, compensation points, and reentrant behaviour. The models, consisting of S = 1 2 spins on a simple cubic lattice, and decorating S = 1 or S = 3 2 spins on the bonds, can be mapped ex

A mean-field approximation is used to study the effects of random crystal field on the critical behaviour of decorated ferrimagnetic Ising model, in which the two magnetic atoms A and B have spins s A ¼ 1 2 and S B ¼ 1, respectively. The results indicate that there may exist some interesting phenome
