چکیده انگلیسی
The spin-1 Ising model is studied for the case of antiferromagnetic (AFM)/AFM interactions on the bilayer Bethe lattice by using the pairwise approach for several values of the coordination numbers q=3q=3, 4 and 6 when the layers are linked with the external magnetic fields. The ground state (GS) phase diagrams, thermal variations of the order-parameters and the response functions are studied in detail to obtain the phase diagrams of the model. It was found that the system gives only one Néel temperature, TNTN, for q=3q=3. Two TNTN's and first-order phase transition temperature, TtTt, thus tricritical point, are found and the existence of two TNTN's leads to the reentrant behavior when q=4q=4 and 6 for some given system parameters.
