Abstract
Using Monte Carlo method, we study the magnetic proprieties of La2FeCoO6 double perovskite. First, we elaborate the ground state phase diagrams in different planes: (R1, R2), (R1, d), (R2, d), (R1, h), (R2, h) and (h, d), where, the reduced parameters R1 = JFe-Fe/JFe-Co, R2 = JCo-Co/JFe-Co, d = Î/JFe-Co and h = H/JFe-Co represent the reduced Fe-Fe, Co-Co exchange coupling interactions, the reduced crystal field and the reduced external magnetic field, respectively. We show that the only stable configurations in these planes are: (±2, ±1/2), (±1, ±1/2) and (0, ±1/2). Then, we investigate the thermal behavior of the magnetizations and the susceptibilities of such a system for the ferromagnetic case. Moreover, we reveal that the increasing exchange Fe-Fe coupling effect increases the critical temperature. We also discuss the hysteresis cycle loops.
