Dislocation scattering and charge transport in copper

Abstract

Galvanomagnetic measurements have been carried out on plastically deformed single-crystal copper specimens. Effective small-angle scattering of the conduction electrons has been found. Point and extended defects, generated for small degrees of low-temperature plastic deformation, change the form of the magnetoresistance both for the open and closed electron trajectories. The scattering of electrons becomes predominantly isotropic for relatively large densities of deformation defects.
