Description
Summary:The stationary state solutions of the Ising-type thin films with different layers in the presence of an external oscillatory field have been examined within the effective field theory. The exhibition focuses on understanding of the external field frequency and amplitude effect on the overall behavior of system for several powerful treatments. The particular attention has been paid on the dynamical parametric evolution of the special point at which the critical temperature of the three-dimensional infinite bulk system, where the surface and the modified exchange parameter are of no importance. Important characteristics of the films, such as surface enhancement phenomenon, effect of thickness on the dynamic process etc. have been introduced together with well known other characteristics. An attempt has been made to explain the relations between the competing time scales (intrinsic microscopic relaxation time of the system and the time period of the external oscillatory field) and frequency dispersion of the critical temperature coordinate of the special point.
