Research progress of practical application of 11 system iron-based superconducting materials

摘要:

自被发现以来,铁基超导体因其较高的临界电流密度、较低的各向异性以及极高的上临界磁场而受到科学家们的广泛关注,具有极好的应用前景,同时也是研究高温超导机制的重要抓手。“11”体系作为结构最简单的铁基超导材料,其不含有毒元素As以及对掺杂敏感等特点使其成为领域内的研究的热点。本文从线带材、涂层导体和薄膜两个角度综述了“11”体系铁基超导材料实用化的研究进展。

Abstract:

Iron-based superconductors have attracted extensive attention from scientists due to their high critical current density, low anisotropy and extremely high upper critical magnetic field since it was discovered. It has excellent application prospects and is also one of the keys to study the mechanism of high temperature superconductivity. As the simplest iron-based superconducting material, the 11 system iron-based superconductor has become a research hotspot in the field due to its characteristics of no toxic element As and sensitivity to doping. In this paper, the research progress of the practical application of 11 system iron-based superconducting materials is reviewed from two perspectives: wire and strip, coated conductor and thin film.
