Spin-Orbit Interaction and Electronic Conduction in Two-Dimensional Disordered Metals

Abstract

Systematic change was observed in the magnetic field dependence of conductivity for the Cu films, Cu–Ag films and Cu–Au films while the temperature dependence is commonly written as σ₀+σ₁ ln T. These features are discussed with theories of localization and the Coulomb interaction in two-dimensional disordered systems. It is shown that the magnetic field dependence is mainly due to the former effect with the spin-orbit interaction and that the temperature dependence is mainly due to the latter.
