  • Patent number: 10217931
    Abstract: Provided is a magnetic element which can generate a skyrmion by a stacked film including a magnetic layer and a non-magnetic layer, and a skyrmion memory to which the magnetic element is applied and the like. Provided is a magnetic element for generating a skyrmion, the magnetic element comprising a two-dimensional stacked film, wherein the two-dimensional stacked film is at least one or more multiple layered films including a magnetic film and a non-magnetic film stacked on the magnetic film. Also, provided is a skyrmion memory including a plurality of the magnetic elements stacked in a thickness direction.
    Type: Grant

  • Patent number: 9400316
    Abstract: An electric current-spin current conversion device according to the invention performs conversion between electric current and spin current utilizing the spin Hall effect or the inverse spin Hall effect of a 5d transition metal. A spin accumulation apparatus according to the invention includes a non-magnetic body in which injected spins are accumulated and an injection unit that injects spins into the non-magnetic body, wherein said injection unit comprises said electric current-spin current conversion device provided on said non-magnetic body, and an electric power source that supplies an electric current to said electric current-spin current conversion device in such a way that a spin current flowing toward said non-magnetic body is generated by the spin Hall effect.
