Critical phenomena in dynamical Ising-typed thin films by effective-field theory

摘要: Abstract The stationary state solutions of the Ising-typed thin films with different layers in presence an external oscillatory field are examined within effective-field theory. study focuses on effects frequency and amplitude overall behavior. Particular attention is paid evolution special point dynamic corresponding to critical temperature three-dimensional infinite bulk system where surface modified exchange parameters no importance. Some findings such as enhancement phenomenon effect thickness process introduced together some other well known characteristics. An attempt made explain relations between competing time scales (intrinsic microscopic relaxation period field) dispersion coordinate point.
