摘要：

A statistical theory is constructed for the quasistatic migration of a domain wall (DW) interacting with highly localized pinning centers. The pinning centers differ as regards statistical distribution over forces W (f). It is shown that neither the prehistory of the DW nor the model of the defect field have much effect on the coercive force. The authors discuss the choices between models of flat or bent domain walls.
