The nonequilibrium dynamic phase transition, in the two-dimensional kinetic Ising model in the presence of a randomly varying (in time but uniform in space) magnetic field, has been studied both by Monte Carlo simulation and by solving the mean-field dynamic equation of motion for the average magnetization. In both the cases, the time-averaged magnetization vanishes from a nonzero value depending upon the values of the width of randomly varying field and the temperature. The phase boundary… 
Nonequilibrium phase transitions and stationary-state solutions of a three-dimensional random-field Ising model under a time-dependent periodic external field.
TLDR
Nonequilibrium behavior and dynamic phase-transition properties of a kinetic Ising model under the influence of periodically oscillating random fields have been analyzed within the framework of effective-field theory based on a decoupling approximation and numerical results indicate that for a bimodal distribution, the dynamic phase diagrams always exhibit a coexistence region in which the stationary state (ferro or para) of the system is completely dependent on the initial conditions.
