摘要: 通过蒙特卡罗方法(MC)与快速傅里叶变换微磁学(FFTM)方法模拟了50 K下钴纳米双环体系的磁化动力学，研究发现，低温时，系统呈现明显的双稳态特征，即“洋葱态”和“涡旋态”，磁滞回线清晰。研究成果对低温磁性纳米环体系计算和低温磁存储技术等领域的应用具有一定意义。
Abstract: The magnetization dynamics of the cobalt dual-nanoring system at 50 K were simulated using the Monte Carlo (MC) method and the Fast Fourier Transform Micromagnetics (FFTM) method. The results indicate that at low temperatures, the system exhibits distinct bistable magnetic behavior, characterized by “onion” and “vortex” states, with well-defined hysteresis loops. These findings are significant for the study of low-temperature magnetic nanoring systems and their potential applications in areas such as low-temperature magnetic storage technologies.
