Embodiment 1
[0024] A superconducting thin film material, composed of the following components according to mass percentage: 2.9% yttrium trifluoroacetate, 5.8% barium trifluoroacetate, 2.5% terpineol, 10.5% acetylacetone, 6.5% acetylacetone Zirconium and the balance niobium. During preparation, mix yttrium hydrochloric acid solution, barium hydrochloric acid solution, titanium hydrochloric acid solution, zirconium hydrochloric acid solution and niobium hydrochloric acid solution evenly, the pH value is between 5.0-6.0, remove water to obtain pure gel; add terpineol to prepare The precursor solution is obtained, and coated on the substrate for low-temperature thermal decomposition; after the treated substrate is heat-treated, it is annealed and heat-treated to obtain a superconducting thin film material.
Embodiment 2
