However, there are still some problems in the preparation and improvement of the properties of iron-based superconductors. In this study, 122-type iron-based superconductors were used as the research object to explore the effects of different preparation methods and conditions on properties. At the same time, experiments on purification and doping treatment were carried out to improve the superconducting properties of the material. The experimental results show that excellent iron-based superconducting wire strip can be obtained under appropriate preparation conditions, and purification and doping treatment can effectively improve its superconducting properties.Keywords: iron-based superconductor; 122-type; wire strip; preparation; property improvement; purification; doping1.讨论背景和意义超导材料是指在低温下电阻等特性急剧变化的材料,其超导性质可以用于制备超导线圈等设备,有着广泛的应用前景。其中,铁基超导体是一类新型超导体,具有高超导转变温度和较强的超导性能,因此在讨论和应用方面备受关注。精品文档---下载后可任意编辑122 型铁基超导体是目前讨论最为广泛的铁基超导体之一,其化学式为 AFe2-xMxSe2(A 为稀土或碱土金属元素,M 为过渡金属元素)[1]。然而,122 型铁基超导线带材的制备和性能提高方面仍然存在着一些问题。因此,对于 122 型铁基超导线带材的制...
