Spin-orbit-torque type magnetoresistance effect element and magnetic memory

Abstract

A spin-orbit-torque type magnetoresistance effect element includes: a first ferromagnetic layer; a second ferromagnetic layer; a non-magnetic layer which is located between the first ferromagnetic layer and the second ferromagnetic layer; and a spin-orbit-torque wiring which has the first ferromagnetic layer laminated thereon, wherein the spin-orbit-torque wiring extends in a second direction intersecting a first direction corresponding to an orthogonal direction of the first ferromagnetic layer, wherein the first ferromagnetic layer includes a first laminated structure and an interface magnetic layer in order from the spin-orbit-torque wiring, wherein the first laminated structure is a structure in which a ferromagnetic conductor layer and an inorganic compound containing layer are disposed in order from the spin-orbit-torque wiring, wherein the ferromagnetic conductor layer contains a ferromagnetic metal element, and wherein the inorganic compound containing layer contains at least one inorganic compound selected from a group consisting of carbide, nitride, and sulfide.
