Zusammenfassung
We report on electrical spin injection from (Ga, Mn) As into a high-mobility two-dimensional electron gas confined at an (Al, Ga) As/GaAs interface. Besides standard nonlocal electrical detection, we use amagneto-optical approach which provides cross-sectional images of the spin accumulation at the cleaved edge of the sample, yielding spin decay lengths on the order of 2 mu m. In some cases we ...
