Universal spin-induced magnetoresistance in the variable-range hopping regime
Universal spin-induced magnetoresistance in the variable-range hopping regime
The magnetoresistance in the variable-range hopping regime due to Zeeman spin-splitting and intra-impurity interactions is calculated analytically and shown to be a universal function of μH/kT log R. Good agreement with numerical calculations in one and two dimensions is observed. With the inclusion of quantum interference effects, excellent agreement with …
