摘要: The nonequilibrium dynamic phase transition, in the kinetic Ising model presence of an oscillating magnetic field, has been studied both by Monte Carlo simulation (in two dimensions) and solving mean-field dynamical equation motion for average magnetization. temperature variations hysteretic loss (loop area) correlation have near transition point. point identified as minimum-correlation becomes maximum above An analytical formulation developed to analyze results. A general relationship among hysteresis loop area, order parameter, also developed.
