摘要：
We consider a model of the aftereffect where the walls are detached from pin defects by vibrations. Dependence is obtained between the activation energy on the external field which is used to estimate the distance between defects, the radius of pin cavity and the stability time in a real film. The calculation is restricted to limp domain walls and ultrathin films with easy perpendicular direction. The model is tested to compare experimental data of the coercive force with a calculated value.
