| Abstract: | For the individual Fe nanorings with the outer diameter of 200 nm,the effect of size upon rings' magnetic properties is simulated by Monte Carlo method.The main contents of the research can be summarized as follows: the magnetization reversal process,the hysteresis loops,the coercivity and so on.The simulated results indicate that,there exist evident size effects on the stability of vortex-type state and magnetization processes of the nanorings. |
