Title: Guoqiang Yu: Innovator in Spin-Orbit Torque Devices
Introduction
Guoqiang Yu is a prominent inventor based in Los Angeles, CA. He has made significant contributions to the field of spin-orbit torque devices, holding 2 patents that showcase his innovative approach to technology.
Latest Patents
His latest patents include an inductive spin-orbit torque device and a method for fabricating the same. This invention relates to a device that utilizes a two-dimensional thin film, which is deposited using chemical vapor deposition (CVD). The method involves sputtering a ferromagnetic material on the thin film, which has an asymmetrical crystal structure. The thickness of the thin film consists of at least one unit-cell layer, with the total number of layers being an odd number. This design allows for reduced device size and fabrication costs by leveraging the vertical magnetic torque generated by the thin film.
Another notable patent focuses on magnetic memory bits with perpendicular magnetization that can be switched by current-induced spin-orbit torques. This invention introduces a basic Spin-Orbit-Torque (SOT) structure that features lateral structural asymmetry, enabling zero-field current-induced switching of perpendicular magnetization. The design incorporates a ferromagnetic layer with a heavy non-magnetic metal layer on one side and an insulator layer on the other, creating a structural mirror asymmetry. The direction of switching is influenced by the applied current and the symmetry breaking in the device.
