Resistivity and microscopic characteristics of platinum in different structural states

Abstract

The experimental temperature dependence of the resistivity of platinum in different structural states is processed using the two-band Mott–Wilson model of a transition metal. It is found that impurities, deformation defects, and quenching defects have essentially different influences on the Debye temperature, the intensity of electron–electron Coulomb scattering, and the intensity of intra- and interband electron–phonon scattering. A number of effective microscopic characteristics and band parameters are calculated in the Friedel model. The mechanisms by which the different structural factors influence the investigated complex of physical characteristics of platinum are analyzed.
