Latest Patents
Among his latest patents is the "Spin valve with thermally stable pinned layer structure having ruthenium oxide specular reflecting layer." This invention features a thermally stable spin valve sensor that achieves an increased GMR ratio by utilizing an antiparallel (AP) pinned layer structure. The first and second pinned layers are separated by an AP coupling layer that includes a nano-oxide layer, which enhances specular scattering and improves the GMR ratio.
Another notable patent is the "Method of forming thin oxidation layer by cluster ion beam." This method involves creating a thin-film magnetic element, such as a TMR element or a spin valve element, on a substrate. The process includes oxidizing a surface portion of a nonmagnetic metal layer using cluster ion beam (CIB) oxidation. This innovative technique allows for the formation of a nano-oxide layer on the nonmagnetic conductive layer, significantly improving the properties of the magnetic element.
