论文摘要
我们使用基于大都市算法的蒙特卡洛模拟（MCS），我们在这项研究中检查了基于稀土的化合物GDN的磁性。第一步，我们讨论和研究了在物理参数不同平面中探索的基态相图。通过比较Eq的哈密顿量建模的能量来说明获得的稳定构型。 （1）。对于非零温度值，我们介绍并讨论了总磁性和敏感性作为：温度，晶体场，交换耦合相互作用和外部磁场的函数的行为。在改变外部磁场的特定值时，会说明和分析磁滞回路：温度，晶体场和交换耦合相互作用。为了完成这项研究，我们介绍了与化合物GDN相对应的关键指数的值。这些结果已与文献中存在的结果进行了比较。
Using Monte Carlo Simulations (MCS), based the Metropolis algorithm, we examine in this study, the magnetic properties of the rare earth based compound GdN. In a first step, we discuss and study the ground state phase diagrams explored in the different planes of physical parameter. The obtained stable configurations are illustrated by comparing the energies modeled by the Hamiltonian of Eq. (1). For non-null temperature values, we present and discuss the behavior the total magnetizations and susceptibilities as a function of: the temperature, the crystal field, the exchange coupling interactions and the external magnetic field. The hysteresis loops are illustrated and analyzed when varying the external magnetic field for specific values of the physical parameters: the temperature, the crystal field and the exchange coupling interactions. In order to complete this study, we present the obtained values of the critical exponents corresponding to compound GdN. Such results have been compared with those existing in the literature.
