Abstract
A system for writing data to and reading data from a magnetic medium utilizing a spin polarized electron beam. One embodiment of the disclosed subject matter may include an array of magnetic locations, each magnetic location including a hard magnetic material sandwiched in between a first and a second layer of a spin-mirror material and a layer of semi-conductor material.
Claims6
A storage structure comprising:
- an array of magnetic locations, each magnetic location including a hard magnetic material sandwiched between a first and second layer of a spin-mirror material and a layer of semi-conductor material;
- and
- wherein the layer of semi-conductor material includes a P-N junction.
A storage structure comprising:
- an array of magnetic locations, each magnetic location including a hard magnetic material sandwiched between a first and second layer of a spin-mirror material and a layer of semi-conductor material;
- and
- wherein the layer of semi-conductor material includes a direct-band semiconductor.
A storage structure comprising:
- an array of magnetic locations, each magnetic location including
- a hard magnetic material sandwiched between a first and second layer of a spin-mirror material
- a layer of semi-conductor material;
- a layer of electrically conductive non-magnetic metal;
- and
- wherein the layer of electrically conductive non-magnetic metal is substantially thin to allow the photons emitted, during operation, by the layer of semi-conductor material to substantially pass through the conductive, non-magnetic metal.
