Monte Carlo simulations of dynamic phase transitions in ferromagnetic thin-films

• Dynamical ferromagnetic Ising-type thin films have been examined.
• Thermal variations of dynamical order parameters have been plotted.
• The profiles of average magnetizations on each layers have been presented.
• Dynamic phase boundaries have been plotted in related planes.
• The variation of crossover point with varying oscillating field amplitude has been presented.

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 reduced exchange interaction (surface to bulk ratio values in RRcR>Rc regimes where RcRc is the critical value at which the critical temperature becomes independent of film thickness LL) have also been taken into consideration. The average magnetizations with varying temperature of each layer are reversed in these two regimes. Based on the results, we have confirmed that the system represents a crossover behavior between ordinary and extraordinary transition in the presence of surface exchange enhancement.
