Temperature dependences of the order parameters of a magnetic Ising superlattice of two ferromagnet materials with spins μ=1/2 and S=1

Abstract

The temperature dependences of the layer parameters σn,z= , mn,z= and qn,z= of a magnetic Ising superlattice consisting of two ferromagnetic Ising materials with spins μ=1/2 and S=1 respectively, on a simple cubic structure, are examined using the effective field theory based on the use of a probability distribution technique that correctly accounts for the single site kinematic relations. According to the values of the exchange interactions, different qualitative types of phase diagrams are expected.
