Abstract
The Landau-Lifshitz equation with the relaxation terms introduced by B ar'yakhtar is discussed. These relaxation terms take into account the spatial dispersion of the relaxation caused by the exchange interactio n and correct symmetry properties of the well known relativistic part of the relaxation term in the Landau-Lifshitz equation. The Slonczewsk i type equation obtained on the basis of this new equation for the dyn amics of the magnetic moment are presented. Some concrete results for the characteristic parameters of the domain wall motion are also given .
