Magnetoresistive determination of localization effects in InSb

Abstract
We have made magnetoresistance measurements in samples of nInSb in the temperature range 0.05-1.5 K. The carrier densities of the samples studied were ∼ 3.1 × 1014 and 2.7 × 1013/cm3. At low fields (H is 0.55 of that expected from theory. Interaction effects could explain the discrepancy. The inelastic scattering localization rate is determined to vary as T3.
