The decorated ferrimagnetic Ising model in a random longitudinal field

Abstract

The effect of a random longitudinal field, on the magnetic properties of a decorated ferrimagnetic Ising model consisting of two magnetic atoms A and B with spins σ A =1/2 and S B =1, is investigated within the framework of an effective field theory based on the use of a probability distribution method. A number of characteristic phenomena, such as the possibility of two compensation points and reentrant behaviour are found.
