Universal spin-induced magnetoresistance in the variable-range hopping regime
Physics Department, Ben Gurion University - Beer Sheva 84105, Israel
Accepted: 3 January 1996
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 . Good agreement with numerical calculations in one and two dimensions is observed. With the inclusion of quantum interference effects, excellent agreement with recent experiments is obtained.
