The Half-Metallic Ferromagnetic behavior of some double perovskites attracts much interest. In this work, we studied the magnetic behavior of the double perovskite Pb2FeReO6. The magnetic atoms are Fe and Re and have the spins S=5/2 and {\sigma}=1, respectively. In a first step, we provide a theoretical study of the ground state phase diagrams .In fact, we present and discuss the stable configurations from the all 6x3=18 possible configurations. Secondly, the magnetic properties of this compound when varying different physical parameters is carried out. Besides, we used Monte Carlo simulations (MCS), under the Metropolis algorithm to provide the magnetic behavior of the studied system as a function of the temperature, the crystal field, the exchange coupling interactions and the external magnetic field. In addition, we studied and discussed the critical temperature of the double perovskite Pb2FeReO6. To complete our study, we presented and analyzed the hysteresis loops for specific values of physical parameters. |
