Outline of Final Research Achievements

We found several novel transition-metal oxides with new functional properties by high-pressure synthesis, epitaxial thin film growth, and topochemical reactions. In a few oxides containing unusually high valence Fe and Co cations, properties such as magnetism, electrical conductivity, and oxide-ion diffusion, were controlled by modifying their cation arrangements and oxygen coordination.

Academic Significance and Societal Importance of the Research Achievements

異常原子価状態を含めた広範な原子価制御の確立とともに、価数変化に応じた構造変化と物性変化から遷移金属酸化物の固体化学を構築する基礎データを得ることができた。また見出された物性変化は、機能特性として応用できるものもあり、電子デバイスのみならず、資源・エネルギー・環境問題の解決に資する新しい機能材料の開発にも繋がるものである。
