  • Patent number: 10998493
    Abstract: A spin-orbit-torque magnetoresistance effect element of the present invention includes: a functional unit, a first ferromagnetic layer whose magnetization direction is configured to be fixed, a second ferromagnetic layer whose magnetization direction is configured to change, and a non-magnetic layer located between the first ferromagnetic layer and the second ferromagnetic layer being laminated therein; a spin-orbit torque wiring which extends in a first direction which intersects a lamination direction of the functional unit and is joined to the second ferromagnetic layer; a heat sink layer which extends in the first direction, is disposed so that the heat sink layer and the spin-orbit torque wiring at least partially overlap when viewed in a plan view from the lamination direction, and is provided spaced from the spin-orbit torque wiring in the lamination direction by a distance of twice a thickness of the functional unit or less in the lamination direction thereof.
