因为Y系超导体比Bi系超导体具有更好的本征高场特性，所以，尽管Bi系材料已能制成长带并有了广泛的应用，但人们仍然竞相研究开发Y系超导线带材的成型工艺。制备Y系带材的方法之一是采用薄膜的制备技术。可以用很多方法制备Y系薄膜，比如物理气相沉积法（PVD），化学气相沉积法 Because Y-based superconductors have better intrinsic high-field characteristics than Bi-based superconductors, there is still a race to research and develop Y-type superconducting tapes despite the fact that Bi-based materials have been made into long ribbons and have been widely used Process. One of the ways to prepare Y-tapes is to use film-making techniques. Y-series thin films can be prepared in many ways, such as physical vapor deposition (PVD), chemical vapor deposition
