Abstract
Electrical spin injection and band offsets in an n-type ferromagnetic semiconductor heterostructure of CdCr/sub 2/Se/sub 4/-AlGaAs-GaAs are studied. Epitaxially grown CdCr/sub 2/Se/sub 4/ films exhibit hysteresis behavior with significant remanence, an in- plane easy axis with a coercive field of 125 Oe. The cross section of the LED and the band alignment were shown.
