Abstract:
1. A method of producing a superconductive material, comprising the steps of: providing a solution of an organic compound of metals whose oxides form a superconductive material; applying the solution onto a surface of a support body; irradiating a surface of the support body opposite to the surface on which the solution was applied with a laser light; conducting a provisional baking step to cause organic components of the organic compound to undergo thermal decomposition and form oxides of the metals; and conducting a main baking step to cause the oxides of the metals to transform into the superconductive material and produce an epitaxially-grown superconductive coating material, wherein the laser irradiation is conducted under the following conditions: J/cm 2 ×a substrate constant, where a substrate constant is defined as a number not less than 1 and dependent on the nature and thickness of the support body; and an irradiation condition area is bounded by straight lines having the following equations where K
