摘要： 基于Zn1-xMnxO纳米薄膜磁性研究的实验结果及相关理论,建立了一个包含多种交换作用的Ising多层膜模型,采用Monte Carlo模拟的Metropolis算法对于其铁磁序的成因进行了模拟研究.结果表明,Mn掺杂浓度(x)越低越有利于铁磁序的形成,但是x越低,系统的磁化强度越小,居里温度越低.载流子对铁磁序的形成所起的调节作用随着x的增大而增强,又随着磁各向异性常数(K)的增大而弱化.本

Abstract： Based on the analysis of ferromagnetic mechanism of diluted magnetic semiconductors (DMSs), an Ising model with multi-exchange interactions is established. The reason of the shape of ferromagnetic order is simulated by Monte Carlo (MC) simulation with the Metropolis algorithm. The result reveals that the lower concentrations of Mn doping (x) are helpful for forming the ferromagnetic order. However, with the lower concentrations of Mn doping the magnetization of the system will be smaller and the Courier temperature will be lower. The modifying efect of carrier on the formation of ferromagnetism is enhanced with the increase of x and the decrease of the anisotropy constant (K). This work predicts that the increase of K will heighten the ferromagnetism and the Courier temperature.
