Abstract
Thin films of the superconductor YBa2Cu3O7−δ (YBCO) were prepared on yttria stabilized zirconia (YSZ) substrates by the dipping-pyrolysis process. The starting solution, produced by dissolving barium and copper naphthenates and yttrium stearate into an organic solvent, was coated on the substrates and heated up to 800 °C. Resistivities of the films were measured by the four probe method and superconduction was observed at Tc = 90 K (onset) and 60 K (end).Keywords
