Abstract

A numerical simulation on dynamic Landau-Ginzburg (η²) ³ model system is performed to investigate the dynamic hysteresis and external field-induced phase transitions. The dynamic symmetry breaking of the free energy is discussed. Centro-symmetry-broken hysteresis is found when the external field is low, which is very different from the high-field behaviors of the hysteresis dynamics. A resonant peak and a saddle back of the hysteresis dispersion curve are observed for the low-field case, which may correspond to two oscillating modes and two resonant characteristic times.
