The investigation of the dynamic phase behavior of a classical Heisenberg spin system with a bilinear exchange anisotropy in a planar thin film geometry by Monte Carlo simulations using different forms for the stochastic dynamics was discussed. Both Glauber and Metropolis dynamics show a continuous dynamic phase transition (DPT) in simulations of the DPT in films subject to a pulsed oscillatory external field with competing surface field. It was observed that the transition region for the DPT as a function of temperature was more extended with Metropolis dynamics. It was shown that the difference arises from a decoupling of the surface and bulk responses of the film near the dynamic phase transition with Metropolis dynamics.
