Outline of Final Research Achievements

We have solved almost all the problems of ferromagnetic semiconductors: 1) Realization of both p-type and n-type ferromagnetic semiconductors by creating Fe-doped III-V ferromagnetic semiconductors, 2) Realization of ferromagnetism in semiconductors at room temperature by raising the Curie temperature Tc above room temperature, optimization of their physical properties and functions, 3) Unified understanding of the origin of ferromagnetism and giving guidelines for materials design. Furthermore, various heterostructures and devices were fabricated to realize and demonstrate useful functions. For example, we discovered a new proximity magnetoresistance effect with a giant magnetoresistance ratio, which was successfully controlled by applying a gate electric field, and we successfully fabricated pn junctions composed entirely of ferromagnetic semiconductors. These results will serve as the basis for the realization of future spintronics devices.

Academic Significance and Societal Importance of the Research Achievements

新しい強磁性半導体を開発し、半導体および磁性物理学、物性物理学とその応用分野の新しい境地を開いた。また本研究の成果は、不揮発性と柔軟な情報処理機能を持つスピントランジスタ、スピン依存バンド構造を用いた量子効果デバイス、トポロジカル状態を用いた機能デバイスなど、低消費電力で動作しかつ革新的な高機能デバイスの実現、につながると期待される。強磁性半導体を中心とする材料開発("強磁性半導体のルネサンス"を起こすこと)によって、将来のニューロモルフィック・コンピューティング(NC)、モノのインターネット化(IoT), 人工知能(AI)に適したデバイスの基盤技術、将来の情報技術の一端を創ることができた。
