Özet

In this work, the ternary alloy (TA) of the form AB(p)C(1-p) with spin-3/2, spin-2 and spin-5/2, respectively, is studied on the Bethe lattice in terms of exact recursion relations in the standard random approach. The bilinear interaction parameter J(AB) is assumed to be ferromagnetic between the nearest-neighbor spins with spin-3/2 and spin-2, while J(AC) is taken to be antiferromagnetic between spin-3/2 and spin-5/2. The possible phase diagrams are obtained from the thermal analysis of the order parameters for the given coordination numbers z = 3,4,5 and 6. This analysis has also revealed that the model gives both second-and first-order phase transitions in addition to the compensation temperatures.
