| 中文摘要 | As an analytical method, the effective-field theory (EFT) is used to study the dynamical response of the kinetic Ising model in the presence of a sinusoidal oscillating field. The effective-field equations of motion of the average magnetization are given for the square lattice (Z = 4) and the simple cubic lattice (Z = 6), respectively. The dynamic order parameter, the hysteresis loop area and the dynamic correlation are calculated. In the field amplitude h(0)/ZJ-temperature T/ZJ plane, the phase boundary separating the dynamic ordered and the disordered phase has been drawn. and the dynamical tricritical point has been observed. We also make the compare results of EFT with that given by using the mean field theory (MFT). (C) 2008 Elsevier B.V. All rights reserved. |
