Spin electronic device i.e. three-bit magnetic shift register, for industrial application, has injector to inject electric current whose intensity is sufficient for providing displacement of magnetic wall in region of free magnetic layer

摘要

The device has free and reference magnetic layers (1, 3) and a non-magnetic layer (2) superposed with each other. A current injector includes a primary electrode (11) arranged above the free magnetic layer, and is arranged in a manner to inject electric current in a direction perpendicular to a plane of the layers, where the current is polarized by the reference magnetic layer, and intensity of the current is sufficient for providing displacement of a magnetic wall (4) in a region of the free magnetic layer located under the electrode of the injector.
