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.
