Abstract
Modern results of band structure calculations are applied to calculate the spin dependence of impurity resistivity within the two-current model of Fert and Campbell. Non-magnetic and transition-metal impurities in Ni and Fe hosts are considered and a qualitatively satisfactory description of the experimental situation is obtained. The adequacy of the Anderson and s-d exchange models is discussed. Effective s-d exchange integrals for impurities with well-defined magnetic moments are estimated. The important role of conduction electron spin polarization in explaining the experimental data is demonstrated. On this basis, the role of d-electrons in conductivity is discussed.
