11 体系铁基超导材料实用化研究进展

Iron-based superconductor has attracted extensive attention from scientists due to its 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 free of toxic element As and sensitivity to doping. In this paper, the research progress of the practical application of 11 system iron-based superconducting materials was reviewed from two perspectives: wire and strip as well as coated conductor and thin film.
