The electroconductivity of the liquid

The concentration dependance of electroresistivity of the liquid binary al-loys of transition metals Fe, Co and Ni is calculated. We considered the contribution to conductivity from the s-electrons, described within the mod-el of nearly free electrons. The role of the partially occupied d-bands is reduced to resonance scattering of the s-electrons on d-states. The inter-action of the s- and d-electrons is described by the hybridization potential of s- and d-states. The interaction with the ions, not including the partially occupied d-states, is described using the pseudopotential of the electron-ion interaction. The electroresistivity of the alloys is calculated in the sec-ond order of the perturbation theory in pseudopotential and hybridization potential. The concentration dependance of electroresistivity of the bina-ry alloys approaches the linear regime as the resonance scattering of the s-electrons on d-states prevails over the scattering on the ions. The calcu-lations exhibit good agreement with the experimental data. Key words: electroresistivity of alloys, liquid transition metal
