Abstract
A transport theory of itinerant ferromagnets at high temperatures is formulated. It is consistent with the modern picture of these materials in which the bands remain spin-split even above the Curie temperature. Interband scattering caused by magnetisation fluctuations is identified as the most important source of dissipation. The temperature dependence and overall magnitude of the electrical resistance of Ni and Fe are computed and found to be in good agreement with experiment.
