摘要：
The electrical resistivity of a disordered ferromagnetic alloy is estimated in terms of the two‐current model. Besides the residual resistivity due to spin dependent potential scattering a spin‐disorder residual resistivity is obtained. A significant T3/2 term associated with incoherent electron magnon collisions and representing large deviations from Matthiessen's rule dominates the temperature dependence of the resistivity below about 10 K. Deviations from Matthiessen's rule arising from the two‐current conduction are discussed. Copyright © 1979 WILEY‐VCH Verlag GmbH & Co. KGaA
