Abstract
Magnetic sensors using spin Hall effect and methods for fabricating same are provided. One such magnetic sensor includes a spin Hall layer including an electrically conductive, non-magnetic material, a magnetic free layer adjacent to the spin Hall layer, a pair of push terminals configured to enable an electrical current to pass through the magnetic free layer and the spin Hall layer in a direction that is perpendicular to a plane of the free and spin Hall layers, and a pair of sensing terminals configured to sense a voltage when the electrical current passes through the magnetic free layer and the spin Hall layer, where each of the push and sensing terminals is electrically isolated from the other terminals.
