Outline of Research at the Start

希土類フリー磁石材料の開発は、我が国のエネルギー戦略における最重要テーマの一つである。軽元素(H,C,O,N)を利用した新しい物質合成法の反応メカニズムを解明するとともに、軽元素がFe合金の磁性に与える影響を理論計算によって解析する。具体的には、出発物質であるFe合金にH、C、O、Nを導入、脱離させることによって酸化物、窒化物等の中間物質を経由させ最終的にこれらの軽元素を含んだ物質を合成する方法に関してその反応メカニズムを解明する。理論計算から導かれる物性とこの新しい物質合成法と組み合わせることにより軽元素を含む希土類フリー磁石の材料設計指針を導出する。

Outline of Final Research Achievements

We have been focusing on the α″- Fe16N2 system and L10-type FeNi alloys, exploring the possibility of improving their properties through the addition of light elements. Through first-principles calculations, it has become evident that both α″-(Fe0.7Co0.3)16(N,C)2 alloy and Fe2Ni2C exhibit a magnetic anisotropy energy (MAE) of approximately 3 MJ/m3 (equivalent to rare-earth magnets), and we have been experimentally working on their synthesis. α″-Fe16N2 as well as Fe2Ni2C are extremely challenging materials to synthesize, but we have managed to accumulate foundational data, including obtaining guidelines towards achieving complete synthesis.
Additionally, in theoretical research, we have been able to develop methods for evaluating the magnetic properties of itinerant electron systems at finite temperatures, enabling the predict of the temperature dependence of MAE in magnetic materials.

Academic Significance and Societal Importance of the Research Achievements

2024年に発足する経済安全保障重要技術育成プログラム「重希土フリー磁石の高耐熱・高磁力化技術」ではL10-FeNiが取り上げられた。米国は同様のプロジェクトを展開しα″-Fe16N2を選択している。我々はFe2Ni2Cが高い一軸異方性定数を有することを初めて理論予測した。またFe2Ni2Cとα″-Fe16N2はその合成が極めて難しい物質であるが、そのキーポイントを把握し完全合成に向けた基礎固めを行った。
