Hysteresis loop analysis to study dynamic phase transition

Abstract

A Monte Carlo study of non-equilibrium phase transition from dynamic ordered to dynamic disordered state is performed using kinetic Ising model in presence of external time dependent sinusoidal magnetic field. Hysteresis loop appears in dynamic phase transition as the instantaneous magnetization usually does not follow the external field. As the temperature around dynamic transition temperature Tc is varied, the shape and orientation of the hysteresis loop change. Studying the change in geometry of the hysteresis loop, the dynamical phase transition is characterized here.
