Abstract: Monte Carlo simulations were performed for magnetization process of torus ring clusters with different radii. Simulation results show characteristic reversal curves which have plateau region in halfway. To investigate the factor that these two curves arise, the change of magnetic spin arrangements in the reversal process were calculated, moreover, closure domain parameters and total energy were analyzed. As a result, it is clear that the two curves are distinguished by a state which is either closure domain state or head-to-head state in halfway of the reversal process. Some clusters with different radii take only one path through closure domain state and the reversal process slightly change. In this paper, the magnetic propertied and relations between reversal process and the radii of clusters are discussed.
