| An analytically tractable simple model of a magnetic domain wall in a ferromagnetic metal is considered and, assuming the ballistic regime of electronic transport, transmission and reflection coefficients of such a wall are calculated within the stationary scattering theory. It is rederived that for realistic values of electron energies and domain wall widths the transmission coefficient is very close to one and thus an ideal domain wall itself (i.e. not taking into account other aspects such as disorder) does not essentially represent a hindrance to the transport. |
