Abstract:
1. A spin-torque oscillation element comprising: a lamination structure comprising a spin injection layer, a non-magnetic interlayer formed on the spin injection layer, and an oscillation layer formed on the non-magnetic interlayer; a non-magnetic conductive layer comprising a non-magnetic conductive material provided on a sidewall of the lamination structure; and an oxide film or a nitride film of a non-magnetic conductive material provided on the non-magnetic conductive layer, wherein an electrical resistivity of the non-magnetic conductive material of the non-magnetic conductive layer is greater than or equal to those of the oscillation layer and the interlayer, wherein an electrical resistivity of the oxide film or the nitride film of the non-magnetic conductive material is greater than that of the non-magnetic conductive material of the non-magnetic conductive layer, and wherein a thickness of the lamination structure in a longitudinal direction is not more than 60 nm.
