Outline of Research at the Start

本研究は,強い磁力と高い構造安定性をもつ結晶の発見を目的とする.そのため応用と学理を両立する物性現象の理解を重視した説明可能なAIと材料科学との融合を図り,磁石材料の開発に寄与する新しい基盤を構築する.希土類磁性材料の探索問題に適用し,系統的に安定な結晶構造を発掘し,構造・安定性・磁性の相関関係を抽出し,高性能磁石の候補材料を提案する.

Outline of Final Research Achievements

We developed an integrated framework of AI and materials science to gain a better understanding of the mechanisms underlying structural properties. Specifically, we systematically explored the candidate space of rare earth-metal (RE)-transition metal (T)-light element (X) crystalline magnetic materials and discovered alternative crystal candidates with high magnetic ability and structural stability. We selected SmFe12, a compound with a ThMn12 structure, as a host lattice due to its excellent magnetic properties. To generate a large number of candidate spaces, we used an automatic generator to substitute elements into each atomic site of the crystalline structure. We established a material search method that integrates first-principles calculations and active learning methods, resulting in the identification of promising candidates for the SmFe12 substitution structures. Our results demonstrate the effectiveness of this approach in discovering new materials with desirable properties.

Academic Significance and Societal Importance of the Research Achievements

本研究は構造物性機構の理解を重視したAIと材料科学の首尾一貫的な枠組みを構築し,RE(希土類金属)ーT(遷移金属・構造安定化元素)ーX(軽元素)結晶性磁性材料の候補空間を系統的に探索し,高磁気能で構造安定性をもつ代替結晶候補を発見することと構造物性科学に対して,理解・応用の両面で貢献するした。特に、ThMn12構造を持つ磁石材料SmFe12化合物に対して、網羅的に結晶構造の各原子サイトに元素を置換を行い、第一原理計算と能動学習手法を統合した材料探索法を確立し、SmFe12置換構造の有望な候補を見つけた。この結果、新規磁石材料の開発に貴重な構造、物性、安定性に関する知見を得ることができた。
