论文摘要
某些双重钙质的半金属铁磁行为吸引了很多兴趣。在这项工作中,我们研究了双钙钛矿PB2FEREO6的磁性行为。磁原子是Fe和Re,并分别具有旋转S = 5/2和σ= 1。第一步,我们提供了基础状态相图的理论研究。其次,在执行不同的物理参数时,该化合物的磁性特性。此外,我们在大都市算法下使用了蒙特卡洛模拟(MCS),以提供研究系统的磁性行为作为温度,晶体场,交换耦合相互作用和外部磁场的函数。此外,我们研究并讨论了双钙钛矿PB2FEREO6的临界温度。为了完成我们的研究,我们为物理参数的特定值介绍并分析了滞后循环。
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 σ=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.
