Superconducting hollow and solid fibers and thin films of YBa2Cu3OX from a polymeric precursor

Superconducting hollow fibers of YBa2Cu3Ox (see figure) can be prepared via the supramolecular organization of polymer-metal complexes. Solid fibers and oriented thin films have also been prepared. The ability to form the superconducting material into different shapes can provide a basis for innovative applications, for instance, the hollow fibers may be used as high-Tc superconducting lenses.
