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(More)
In principle there are a few possible configurations for tilted magnetic recording including the usage of tilted media in a longitudinal recording system, the usage of tilted media in a perpendicular recording system using single pole head, and the usage of the tilted single pole head with a perpendicular medium. We will discuss the advantages and(More)
