%X 基于蒙特卡洛(MC)方法与快速傅里叶变换微磁学(FFTM)方法，研究了厚度不同钴纳米环的磁化特性。模拟结果表明，纳米环堆叠时，系统的磁化过程存在“双稳态”特征，在磁化翻转过程中出现局部涡旋态，随着厚度的变化，系统的自旋组态出现了更为丰富的过渡态，整体的磁化过程更加复杂。<br />
Based on Monte Carlo (MC) method and Fast Fourier transform micromagnetics (FFTM) method, the magnetization characteristics of cobalt nanorings with different thickness were simulated. The simulation results show that the magnetization process of the system is bistable, and the local vortex state appears in the magnetization reversal process. With the change of the thick-ness, the spin configuration of the system appears more abundant transition states, and the overall magnetization process becomes more complex.
