SPIN SWITCH AND MAGNAETIC STORAGE ELEMET USING IT

摘要

A spin switch driven under a voltage, comprising a ferromagnetic element, a magnetic semiconductor magnetically coupled with the element, an antiferromagnetic element magnetically coupled with the magnetic semiconductor, and an electrode connected with the magnetic semiconductor via an insulator, wherein the magnetic semiconductor reversibly changes between ferromagnetic and paramagnetic with a change in an electrode potential, and a ferromagnetic element formed when the magnetic semiconductor is changed to ferromagnetic is magnetized in a specified direction by a magnetic coupling with the magnetic semiconductor .
