Abstract:
1. A magnetic recording device comprising: a laminated body laminating: wherein spin-polarized electrons are generated by a current passing the first ferromagnetic layer, the current passing in a direction generally perpendicular to a film plane of layers of the laminated body, wherein the first nonmagnetic layer and the second nonmagnetic layer are spin transfer layers for transferring spin information, wherein the magnetization direction of the second ferromagnetic layer is determinable in response to an orientation of the current, by the spin-polarized electrons acting on the second ferromagnetic layer, wherein the magnetization of the third ferromagnetic layer is able to undergo precession by the spin-polarized electrons passing the third ferromagnetic layer, and a magnetic field is generated by the precession acting on the third ferromagnetic layer.
