Research Abstract

A highly efficient spin-polarized electron source or spin source is a key element for spintronic devices, in which both the charge and the spin of the electron are utilized as the information carrier. Heusler alloys thin films have attracted much interest as spin sources because of the half-metallic nature theoretically predicted for many of these alloys. It was found that detrimental defects can be reduced by appropriately controlling the film composition of Heusler alloys. It was also shown that the suppression of detrimental defects led to a significant enhancement of the half-metallic nature of Heusler alloy thin films in device structures. Excellent device characteristics were demonstrated for fabricated magnetic tunnel junctions with Heusler alloy electrodes and a MgO barrier by improving the interfacial structures in addition to the above-mentioned enhancement of the half-metallic nature.
