Transport through zincblende magnetic semiconductors with magnetic domainwalls is studied theoretically. We show that these magnetic domain walls havean intrinsic resistance due to the spin-orbit interaction. The intrinsicresistance is independent of the domain wall shape and width when the latter islarger than the Fermi wavelength. For typical parameters, the intrinsic domainwall resistance is comparable to the Sharvin resistance and should beexperimentally measurable.
