自从一九五四年马赛厄斯等人发现 Nb_3Sn,以及围绕着其在高磁场中保持超导性的现象进行研究以来,很多作者已叙述了把这种材料制成一种适于绕入高场磁体的形状的一些方法。这些包括有“KunzLe 线”的制取,在一隋性基体上气相沉积 Nb_3Sn,以及在一铌基体上扩散生成 Nb_3Sn。目前,一些较重大改进之一是提高了在 Nb_3Sn 层中可获 Since Matthias et al. Discovered Nb_3Sn in 1954 and studied their phenomena of maintaining superconductivity in high magnetic fields, many authors have described the use of this material as a material that is suitable for rounding high Some ways of shaping the field magnet. These include the “KunzLe line” preparation, vapor deposition of Nb_3Sn on an inert substrate, and diffusion onto a niobium substrate to produce Nb_3Sn. At present, one of the more significant improvements is the increased availability in the Nb3Sn layer
