Abstract :
A Monte-Carlo algorithm for dynamic hysteresis simulation in Q-state Potts spin lattice is developed and a detailed investigation on Q-dependence of the hysteresis is performed. It reveals that a significant dependence of the hysteresis pattern on the number of the spin states in lattice is identified and the decayed oscillation of both remanence and coercivity with Q is established. This dependence is explained using a simple geometric model. In addition, a series of parameters characterizing the hysteresis pattern and domain boundaries, as a function of Q and external field, are simulated and discussed.
