ABSTRACT

The aim of this paper is to investigate the magnetic properties of phosphorene-like nano-structure applying the Metropolis Monte Carlo simulations. Based on the spin mixed system σ = 7/2 and S = 2, we have analysed the variation of the magnetic phase states in the absence of temperature and the magnetizations of the compound with temperature for the mixed spins phosphorene. We also studied the effect of varying other parameters such as the exchange coupling interactions, the temperature, the external magnetic field and the crystal fields on the total and partial magnetizations. Besides, we have discussed the effect of each parameter on the critical temperature of the system. Finally, we have presented the magnetic hysteresis cycles, for different values of crystal field, exchange coupling interactions and temperature.

摘要

本文的目的是应用 Metropolis Monte Carlo 模拟研究类磷烯纳米结构的磁性。基于自旋混合系统σ  =  7/2 和S  = 在图2中，我们分析了混合自旋磷烯在没有温度的情况下磁相态的变化以及化合物的磁化强度随温度的变化。我们还研究了改变其他参数的影响，例如交换耦合相互作用、温度、外部磁场和晶体场对总磁化强度和部分磁化强度的影响。此外，我们还讨论了每个参数对系统临界温度的影响。最后，我们提出了磁滞循环，对于不同的晶体场值、交换耦合相互作用和温度。
