Method and device for magnetizing thin films by the use of injected spin polarized current

摘要

A device and method for magnetizing a material having a magnetic constituent. In a preferred embodiment, a ferromagnetic film and a first film are selectively deposited at first and second locations on the material. The ferromagnetic film is magnetized in a first direction. A voltage source is coupled between the ferromagnetic and first films to enable a spin-polarized current to flow through the material to magnetize the material.
