Patent ID: 7961439

Claim:
A high-frequency oscillation element, comprising: a first magnetic material exhibiting thermal fluctuation of magnetization which generates spin fluctuation in conduction electrons; a nonmagnetic conductive material which is laminated on the first magnetic material and transfers the conduction electrons; a second magnetic material which is laminated on the nonmagnetic conductive material, generates magnetic resonance upon injection of the conduction electrons, and effects magnetic dipole interaction to magnetization of a neighboring magnetic area by means of magnetic vibration stemming from the magnetic resonance, wherein the second magnetic material comprises a plurality of ferromagnetic layers and a plurality of nonmagnetic layers alternately sandwiched between the plurality of the ferromagnetic layers, and wherein the ferromagnetic layers adjacent to each other with a respective one of the nonmagnetic layers therebetween are antiferromagnetically coupled to each other; a first electrode electrically coupled with the first magnetic material; a second electrode electrically coupled with the second magnetic material; and a non-magnetic barrier provided between the second magnetic material and the second electrode, the non-magnetic barrier being in contact with the second magnetic material and in contact with the second electrode; wherein the high-frequency oscillation element performs high-frequency oscillation by passing conduction electrons between the first magnetic material and the second magnetic material so that a magnetic procession occurs in at least one of the first magnetic material and the second magnetic material, thereby inducing magnetic resonance.
