Outline of Final Research Achievements

Computational frameworks for atomic arrangements and magnetic properties of nanostructures including magnetic elements and heavy elements were developed. Applications are made for interfaces between ferromagnetic Heusler compounds and BaTiO3. Relation between interface atomic structures and magnetic properties were clarified. In addition, strain effects due to the change in the electric polarization on magnetic properties were identified.
Furthermore, a new theoretical method for finite temperature magnetism was developed on the basis of first-princples electron theory.

Academic Significance and Societal Importance of the Research Achievements

磁性元素と重元素の協奏による新奇な物性を理論解析する技術基盤を確立し,ナノ界面の第一原理電子論による理論解析を実行した。ますます微細化の進む電子デバイスでは,電界による磁性の制御など,新しいデバイス動作原理が求められている。白金族や希土類に頼らずとも界面磁気異方性を大きくできる可能性を本研究成果は示しており,重元素を活用した磁性材料の高性能化への一助となることが期待される。
