Research Abstract

A material that is both a magnet and a semiconductor can be utilized as a new type of transistor, in which we can control the "up" and "down" spins as well as the electric charge of carriers. Such a transistor has an advantageous point when compared with a conventional transistor based on silicon, because the "spin-transistor" consumes less electric power. Also, although a "transparent" magnet is useful for the control of an optical signal, a material that can be a device working well in the ultraviolet to blue region, i.e., a wavelength range of emission from GaN-based laser diodes, has not been developed. In the present study, we have succeeded in fabricating novel magnetic oxide thin films with magnetic, electrical, and optical functions. In particular, we emphasize that we could prepare magnetic oxide thin films with potential functions for spintoronics applications by using abundant minerals present in the earth's crust.
