Abstract
The model of the magnetic binary alloy which contains interacting itinerant electrons and localized spins was considered. The interaction between both kinds of electrons was assumed in the simple local exchange form. The complicated many body problem was reduced to the one particle one with the help of Coherent Potential Approximation (CPA ). Itinerant electron selfenergy was calculated using standard Green's function technique with taking into account short range order (SRO ) within the localized spin system. Electron's states were strongly affected by the correlations (SRO , when T > T ~C~) within localized moments system. The DC electrical conductivity σ in the paramagnetic region expressed by Kubo‐Grennwood alloy formula was calculated. The resistivity ρ = 1/σ and its derivative over the temperature have the structure near T ~C~, which depends on the number of the electrons in the band and the interaction strength between two subsystems. The quantities ρ , $ { {\partial \rho} \over {\partial T} }$ were not constant vs. temperature as it is in the simple models. The influence of the important model parameters on the DC conductivity was also discussed. (© 2006 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
