ABSTRACT:
Method of applying in accordance with a pattern thin layers of oxidic superconductive material onto a substrate, it not being necessary to subject the superconductive material to mechanical or chemical treatments. At its surface the substrate is provided in accordance with a desired pattern with two different material compositions. The first composition is chosen such that the oxidic material applied thereon is superconductive at a desired surface temperature. The second composition is chosen such that the oxidic material applied thereon is not superconductive.
