Outline of Research at the Start

超電導は、抵抗ゼロで大電流を流せるため送電、発電、蓄電や電動機など次世代電気機器応用に期待されている。応用上重要な臨界電流密度(Jc)を理論限界であるクーパー対が壊れる対破壊電流値(Jd)の最大40%まで向上させることを目的に、本研究では、独自の非超電導相導入技術に加えて、『ナノひずみとキャリア』を人工制御するすることでJcを最大にする超電導材料設計の指針を確立する。

Outline of Final Research Achievements

Superconductor is expected to be applied to next-generation electrical applications such as power transmission, power generation, energy storage, and electric motors because it can pass large currents with zero resistance. An improvement in critical current density (Jc) is an important characteristic as well as critical temperature (Tc) for the applications. In this work, for maximizing Jc, we combine (1) nano-sandwich strain introducing technology and (2) carrier density control technology, in additon to depeloped method to introducing artificial pinning centers. Furthermore, the new material design will be applied to other superconducting and functional electrical materials.

Academic Significance and Societal Importance of the Research Achievements

SDGsやSociety5.0社会に役立つイノベーションに未だ超伝導が貢献できていないのは高価な液体ヘリウム温度まで冷やさなければ超伝導にならない金属系超伝導線材が用いられているためである。一方、無尽蔵かつ低コストな液体窒素で超伝導になるCu酸化物超伝導薄膜線材は、磁場中Jc特性は応用に求められる特性に達していない。本研究で実施するJcを最大にする超電導材料設計指針により低コストである液体窒素温度下で超伝導応用に必要とされるJc特性まで向上させる。さらに本指針により、既存材料だけでなく新超伝導材料のJcを飛躍的に向上させ、革新的超伝導応用により社会に貢献する。
