Bloch-Boltzmann analysis of electrical transport in intermetallic compounds: ReO3, BaPbO3, CoSi2, and Pd2Si

Abstract

The shape and magnitude of the electrical resistivity ρ(T) is analyzed for four intermetallic compounds, and electron-phonon coupling constants λ are extracted. ${\mathrm{ReO}}_3$ is particularly interesting because a sharp departure from the Bloch-Grüneisen shape can be attributed to high-frequency optical vibrations. The λ values for the oxide metals seem too large to be consistent with the absence of superconductivity, but the results generally agree well with a conventional Fermi-liquid interpretation. The Hall coefficient ${\mathit{R}}_{\mathit{H}}$ of ${\mathrm{ReO}}_3$ is found to agree well with theory.
