Abstract

Abstract In this paper, we study the critical magnetic properties of the Half Heusler alloy RhCrSi, using Monte Carlo simulations (MCS) under the Metropolis algorithm. In fact, to study this alloy, we apply an Ising model using the MCS simulations, we concentrate only on the magnetic atoms: Rh and Cr. For this purpose, these magnetic atoms are modeled by the spin moments S = 5/2 for Rh atoms and σ = 2 for Cr atoms, respectively. In addition, we discuss the ground state phase diagrams in different planes corresponding to different physical parameters. On the other hand, for non-null temperature values, we perform the Monte Carlo simulations (MCS) to study the critical behavior of the compound RhCrSi, in the Ising approximation. Indeed, we present a detailed discussion of the obtained results for the magnetizations as a function of the temperature, the crystal field and the exchange coupling interactions. Additionally, we give the reliance of the basic temperature as an element of precious crystal field when fixing the exchange coupling interactions. To finish this work, we built up and examined the magnetic hysteresis cycles and the relating coercive fields as a part of the external magnetic field.

半Heusler合金RhCrSi的临界磁性行为:蒙特卡罗研究

摘要本文采用蒙特卡罗模拟(Monte Carlo simulation, MCS)方法，在Metropolis算法下研究了半Heusler合金RhCrSi的临界磁性能。事实上，为了研究这种合金，我们使用了一个Ising模型来使用MCS模拟，我们只关注磁性原子:Rh和Cr。为此，这些磁性原子分别由Rh原子的自旋矩S = 5/2和Cr原子的自旋矩σ = 2来建模。此外，我们还讨论了不同物理参数对应的不同平面的基态相图。另一方面，对于非零温值，我们执行蒙特卡罗模拟(MCS)来研究化合物RhCrSi在Ising近似下的临界行为。实际上，我们详细讨论了所得的磁化强度与温度、晶体场和交换耦合相互作用的关系。此外，在确定交换耦合相互作用时，我们给出了基本温度作为宝贵晶体场的一个因素的依赖关系。为了完成这项工作，我们建立并检测了磁滞循环和相关的矫顽力场作为外磁场的一部分。
