Abstract

The invention relates to a method for producing a composite comprising a high-temperature superconductor (HTS) layer based on rare earth metal-barium-copper oxide on a substrate with defined biaxial texture, having the following steps: applying a first HTS coating solution to the substrate, drying the first HTS coating solution to produce a first film, pyrolyzing the first film to produce a first pyrolyzed sublayer, removing an interfacial layer on the upper side of the first pyrolyzed sublayer to produce a first pyrolyzed sublayer with reduced layer thickness, applying a second HTS coating solution to the first pyrolyzed sublayer with reduced layer thickness, drying the second HTS coating solution to produce a second film, pyrolyzing the second film to produce a second pyrolyzed sublayer, optionally forming one or more further pyrolyzed sublayers on the second pyrolyzed sublayer, and crystallizing the overall layer formed from the pyrolyzed sublayers to complete the HTS layer, wherein the removal of the interfacial layer in step D) is effected in such a way that a texture determined by the defined biaxial texture of the substrate is transferred to the first and also to the second …
