  • Skyrmion diode and method of manufacturing the same
    Patent number: 11024726
    Abstract: The present disclosure provides a skyrmion diode using skyrmions as information carriers. The skyrmion diode includes a magnetic body and a conductive body. The magnetic body has a skyrmion which is used as information carrier. The conductive body is disposed on or under the magnetic body. The conductive body includes a Dzyaloshinskii-Moriya interaction (DMI) region and a defect region. The DMI region is provided to induce DMI in a region of the magnetic body corresponding to the DMI region by the spin-orbit coupling of the conductive body and magnetic moments of the magnetic body. The defect region is provided to prevent the DMI from being induced in a region of the magnetic body corresponding to the defect region.
    Type: Grant
