Abstract: The dynamic hysteresis in two-dimensional multi-domain spin systems is simulated using Monte-Carlo method based on Q-state planar Potts model. The pattern and scaling property of the hysteresis as a function of the oscillating time-varying external field are studied and compared qualitatively with the experimental data on PZT ferroelectric films and theoretical predictions. While the scaling of the hysteresis area with frequency f and amplitude E0 of the external field at a form of f1/3E02/3 over the low-f range is well-established, the high-f range scaling relations as derived from the simulation, experiment and theoretical model differ from one and another.
