The invention relates to a method for producing a composite comprising a high-temperature superconductor (HTS) layer on the basis of rare earth metal barium copper oxide on a substrate having a predefined biaxial texture, comprising the following steps : applying a first HTS coating solution to the substrate, drying the first HTS coating solution to produce a first film, pyrolysing the first film to produce a first pyrolysed partial layer, removing a boundary layer on the top side of the first pyrolysed partial layer to produce a first pyrolysed partial layer having a reduced layer thickness, applying a second HTS coating solution to the first pyrolysed partial layer having a reduced layer thickness, drying the second HTS coating solution to produce a second film, pyrolysing the second film to produce a second pyrolysed partial layer, if appropriate forming one or a plurality of further pyrolysed partial layers on the second pyrolysed partial layer and crystallising the overall layer formed from the pyrolysed partial layers to complete the HTS layer, wherein removing the boundary layer in step D) is carried out in such a way that a texture is transferred into the first and also into the second pyrolysed partial layers, said texture being determined by the predefined biaxial texture of the substrate, and also a product producible by such a method.
