The resistance is calculated by use of Landauers formula. The result is shown to agree with the result of the linear response theory if the equilibrium is assumed in the four-terminal case 关键词: magnetic domain walls;magnetoresistance;nanostructured materials;domain wall resistance;Landauers formula;electron scattering;nano-wire;linear response theory;four-terminal case;mesoscopic magnet;magnetoresistance
