摘　　要：铁基超导体具有极高的上临界磁场、较小的各向异性、简单的制备工艺等优点,在高场超导磁体、核磁共振谱仪、可控核聚变装置、高能粒子加速器等领域具有重要的应用前景。为满足上述高场强电应用需求,必须制备出高性能超导线带材。文章详细介绍了多种体系铁基超导线带材的研究进展,分析当前线带材研究中存在的问题,提出改善线材传输性能的途径,并对铁基超导线材的发展趋势进行展望。Iron-based superconductors have many attractive properties such as high critical field,small anisotropy,and ease of fabrication,so they have great potential for future use in ultra-high field magnets,nuclear magnetic resonance spectrometers,controllable fusion devices and high energy particle accelerators.For these electrical applications it is very important to develop wires and tapes with a large current carrying capacity.Here we provide a background introduction and review recent achievements in the fabrication of iron-based superconducting wires and tapes.Current problems that still have to be solved are discussed,and further improvements for large-scale applications are proposed.
