Outline of Final Research Achievements

A new insulating highly thermal conducting material using the large thermal conductivity due to magnetic excitons, so-called thermal conductivity due to spins, is expected. Accordingly, the studies of Ca2FeO3Cl and LaSrFeO4 were performed to develop and investigate new materials with the large thermal conductivity due to spins.
Although the single crystal of Ca2FeO3Cl was not obtained, the single crystal of LaSrFeO4 was successfully obtained. As a result of the thermal conductivity measurements, the large thermal conductivity due to spins was observed and obtained the new guideline to a highly thermal conducting material and the knowledge of mechanism of the thermal conductivity due to spins.

Academic Significance and Societal Importance of the Research Achievements

大きなスピンによる熱伝導を持つ新しい物質を発見することができた。これにより、今まで考慮されていなかった物質群においても、大きなスピンを持つ可能性が示された。さらに、新しいスピンによる熱伝導機構の知見を得ることができ、大きなスピンによる熱伝導を持つ物質の新しい指針を得ることができた。以上により、本研究は、絶縁性高熱伝導材料への応用に貢献する社会的意義があり、スピンによる熱伝導機構解明に向けての学術的意義がある。
