Ferromagnets perturbed by time-dependent fields are technologically important examples of nonequilibrium physics. Using kinetic Monte Carlo simulations and droplet theory of magnetization reversal, the authors explain recent experiments on ordered uniaxial ferromagnetic films driven by oscillating fields. The associated dynamic phase transition at a critical field period is known to be in the equilibrium Ising universality class. Consistent with experiments, the authors find that the response to a constant bias field in the supercritical period limit differs from an equilibrium ferromagnet above criticality in that, instead of a wide central susceptibility maximum, side bands are observed, which are shown to result from stochastic resonance.
