Study of the magnetic properties of the perovskite CeFeO3: Monte Carlo Simulations

In this study, we investigate the magnetic properties of the perovskite CeFeO3, using Monte Carlo Simulations (MCS). This perovskite is modeled by a mixed spin system (5/2, 3/2). In a first part, we have investigated the effect of different physical parameters on the stability of different phases. From 6x4 = 24 possible phases, we found twelve (12) stable phases in the exchange coupling interaction plane. On the other hand, we have inspected the thermal behavior of the magnetizations and the by using MCS. In fact, we have analyzed and presented the effect of the crystal field, the exchange coupling interactions and the external magnetic field on our system. For very low temperature values, the total magnetization reaches its maximum value. This is in good agreement with the ground state phase diagram. The magnetic susceptibility of the perovskite CeFeO3 reaches its maximum value showing a peak at the specific temperature Tc ˜ 12 K. To complete our study; we presented and analyzed the hysteresis loops for specific values of the physical parameters.
