Effect of random crystal field on a doubly decorated ferrimagnetic Ising model

Abstract

Within the framework of the mean-field approximation, we discuss the effects of random crystal field on magnetic properties of the doubly decorated ferrimagnetic Ising model, in which the two magnetic atoms A and B have spins б = ±1/2 and S = ±1, 0, respectively. Also, the effect of the exchange interaction, between nearest neighbor decorating points, on the compensation temperatures is discussed. Furthermore, the appearance of the partly ferrimagnetic phase (m б = −1/2, m s = 1/2) exhibits different types of phase diagrams.
