Abstract
By means of detailed Monte Carlo (MC) simulations, we have presented dynamic phase transition (DPT) properties of ferromagnetic thin-films. Thermal variations of surface, bulk and total dynamical order parameters (DOP) for a film and total order parameter for the films with different thicknesses have been examined. Opposite regimes of the critical value of reduced exchange interaction (surface to bulk ratio) at which the critical temperature becomes independent of film thickness has been also taken into consideration. The average magnetizations of each layer is reversed in these regimes. Based on the results, we have confirmed that the system represents a crossover behavior in between ordinary to extraordinary transition in the presence of surface exchange enhancement.
