Spin-Orbit Assisted Variable-Range Hopping in Strong Magnetic Fields
arXiv:cond-mat/9607211 · doi:10.1209/epl/i1997-00121-4
Abstract
It is shown that in the presence of strong magnetic fields, spin-orbit scattering causes a sharp increase in the effective density of states in the variable-range hopping regime when temperature decreases. This effect leads to an exponential enhancement of the conductance above its value without spin-orbit scattering. Thus an experimental study of the hopping conductivity in a fixed, large magnetic field, is a sensitive tool to explore the spin-orbit scattering parameters in the strongly localized regime.
