摘要：

The effect of the Rashba-type spin-orbit interaction on the domain-wall (DW) magnetoresistance (MR) is investigated for a smooth linear DW within the semiclassical approach. Results of this study are indicative of a negative MR for current-in-wall geometry for some ranges of the impurity densities and the chirality dependence of the DW MR. The increase of the Rashba coupling strength can effectively increase the MR of the DW in the samples with low impurity concentrations.
