Domain wall (DW) resistance in perpendicularly magnetized (Ga,Mn)As has been investigated. The observed DW resistance is decomposed into extrinsic and intrinsic contributions. The former is explained quantitatively by the zig-zaging current due to an abrupt polarity change of the Hall electric field at DW. The latter is consistent with the disorder-induced mixing of spin channels due to small non-adiabacity of carrier spins subject to spatially varying local magnetic moment and is shown to be an order of magnitude greater than a contribution from anisotropic magnetoresistance.
