    • Disclosed is a method for forming a superconductive oxide layer on a substrate. The method comprises applying a precursor solution to a major surface of the substrate such that a metal-containing layer is formed on the surface, and heat treating the substrate/layer combination such that at least a substantial portion of the layer material is transformed into superconductive oxide. Exemplarily, the precursor solution is formed by dissolving Ba--, Y--, and Cu-containing compounds in acetic acid and water, spinning the solution on a MgO substrate, driving of unwanted constituents of the resulting layer at 400.degree. C., heating the combination to about 830.degree. C. in O.sub.2 such that the (perovskite) phase that is associated with superconductivity in YBa.sub.2 Cu.sub.3 O.sub.7 is formed, and oxygenating the layer at about 400.degree. C. in O.sub.2.
    • 公开了一种在基板上形成超导氧化物层的方法。 该方法包括将前体溶液施加到基底的主表面上,使得在表面上形成含金属层,并对基底/层组合进行热处理,使得至少大部分的层材料转变为超导 氧化物。 示例性地,通过将​​含有Ba,Y和Cu的化合物溶解在乙酸和水中形成前体溶液,将溶液纺丝在MgO基板上,在400℃下驱动所得层的不想要的成分,加热 在O 2中组合至约830℃,使得形成与YBa 2 Cu 3 O 7中的超导性相关的(钙钛矿)相,并在约400℃下在O2中使该层氧化。
