Outline of Final Research Achievements

We have developed international collaboration scheme for the study of the f-electron materials with the collaboration of IMR Took University, Charles University (Czech Republic), Academy of Sciences of the Czech Republic, CEA (France), and CNRS-National High Magnetic Field Laboratory (France). We have succeeded in growing several high-quality single crystals. The electronic properties of the several rare-earth and actinide compounds have been investigated under high pressures. Exotic electronic properties such as, pressure induced valence transition, enhancement/suppression of magnetism etc. were observed. Besides a new type of diamond anvil type pressure cell is also constructed for SQUID magnetometer. It will be quite useful for quick survey of the stability of ferromagnet and superconductors under high pressures.

Academic Significance and Societal Importance of the Research Achievements

強相関電子系の中でもアクチノイド化合物に関する研究は各国で行われているものの、その軍事利用、商業的利用、そして安全管理の観点からその取り扱いだけでなく、使用や運搬などにあたるまで厳重に管理されている。本課題では、国際共同研究により、独立に研究を行っていた日本、チェコ、フランスの５機関について結晶育成から物性測定までを連携して行う国際共同研究の枠組みを構築したことで、UIrSi3や新しく見つかった超伝導体UTe2などの研究を速やかに行うことができた。人材育成や人材交流の観点からも大きな成果を得ることができた。
