Local magnetization and magnetotransport in magnetic semiconductors

Abstract

We describe the influence of local magnetization on electron localization in magnetic semiconductors. This includes a review of the magnetic field induced insulator-metal transition in Gd3-xvxS4 (where v=vacancy) and the observation of activated transport, i.e. a 'hard' gap, in the hopping regime for the diluted magnetic semiconductor Cd1-xMnxTe:In. © 1994.
