Effects of strain on orbital magnetic and spin paramagnetic susceptibilities in metals

Abstract

Linear dependence on strain of the orbital magnetic and spin paramagnetic susceptibility tensors for Bloch electrons in metals are derived. The results are applied to a metal with cubic symmetry before deformation. An anisotropic orbital magnetic susceptibility tensor and a paramagnetostriction tensor as well as spin contribution are obtained for a deformed crystal. The orbital and spin contribution to the volume paramagnetostriction are calculated for a single crystal and those contributions to the volume dependence of the total magnetic susceptibility for a polycrystalline sample are also given.
