Abstract In three-dimensional {ital n}-CdSe samples that obey Mott variable-range hopping, {rho}={rho}{sub 0}exp({ital T}{sub 0}/{ital T}){sup 1/4}, in the absence of a magnetic field, we report a field-induced crossover at low temperatures to a resistivity that exhibits a weak power-law divergence, {rho}={rho}{sub 0}{ital T}{sup {minus}{alpha}}, with an exponent {alpha} that decreases slowly with increasing field. {copyright} {ital 1996 The American Physical Society.}
