Abstract
Abstract The contribution of Bloch‐wall electron‐scattering to the electrical resistivity of a ferromagnetic metal is calculated. Calculations are carried out for various cases which include small as well as large exchange splittings. In all cases, spherical Fermi surfaces are considered, the wall width is assumed to be small compared to the intrinsic electron mean‐free‐path and diamagnetic effects are neglected. It is found that the experimental results (large negative magnetoresistance between 0 and 100 G) could be explained, even when diamagnetic effects are not included, if the majority and minority spins have sizeably different density‐of‐states at the Fermi level.
