“…The critical behavior of both semi-infinite spin-1/2 and spin-1/2 Ising film in a random transverse surface field has been studied within the EFT [29]. The FM multilayers consisting of two materials in a sandwich structure (ABA) using an EFT with a probability distribution technique that accounts for the self-correlation function [30]. The finite size transfer matrix method and MFT were used to study the layering transitions for an Ising model under uniform and variable magnetic field in a film of finite thickness limited by a single substrate [31].…”

The phase diagrams of spin-1/2 Ising model on a two-layer Bethe lattice with antiferromagnetic interactions for each layer and either antiferromagnetic or ferromagnetic interaction between the layers are investigated by using the pairwise approach for given values of coordination number q. The exact expressions of the order--parameters, response functions and free energy are obtained in terms of the recursion relations. The ground-state phase diagrams are calculated for given system parameters of the model. In the guidance of the ground-state phase diagrams, the temperature dependent phase diagrams of the model are also studied in detail for given coordination numbers q = 3, 4 and 6. It was found that the system presents only second-order phase transitions with different thermal behaviors for all values of q. In addition, two Néel temperatures, T N , are found for q = 6 only.
