	采用Monte Carlo (蒙特卡罗)方法研究了体系温度为100 K时纳米环的磁特性。研究发现，低温下系统依然保持“双稳态”特征，即存在“洋葱态”和“涡旋态”。但低温纳米环的矫顽力比常温纳米环的矫顽力大。系统的自旋组态可以清晰的展示出系统的磁化过程。<br />
Base on Monte Carlo method, the magnetic properties of the nanorings at system temperature of 100K are studied. It is found that the systems still remain bistable states at low temperature; that is, there are “onion-type-states” and “vortex-type-states”. However, the coercivity of low temperature nanorings is higher than that of normal temperature nanorings. The spin configurations of the system clearly show the magnetization process of the system.
