Abstract
A drift motion of kinks in the phi(4) model, induced by an oscillating external field, is investigated and the expression for nonlinear mobi lity coefficients is obtained. The general theory is applied to the co ncrete system described in the framework of the phi(4) model, namely, to the drift of a small-angle domain wall in an easy-axis ferromagnet near the reorientation phase transition.
