Effects of spin-orbit scattering on the magnetoconductance in variable-range hopping

We analytically study the effect of spin-orbit (SO) scattering on the hopping transport of strongly localized electrons in a magnetic field. Closed-form results for the magnetoconductance (MC) in the limit of strong SO scattering are derived for quasi-1D and 2D systems. The MC is positive with reduced magnitude and identical periodicity compared to that without SO scattering. Moreover, we provide a simple formula for the field strength that first saturates the MC. The MC for 3D systems in a weak magnetic field of arbitrary orientations is also obtained analytically, which shows MC anisotropy and thus enables us to determine the direction of the critical hop.
