Preparation of YBa2Cu3Ox Thin Film by Flame Pyrolysis

Abstract
YBa2Cu3O x thin films were prepared by flame pyrolysis. The X-ray diffraction analysis showed that as-prepared films had a strong preferred orientation with the c-axis perpendicular to the film plane. Film resistivities showed a sharp transition at temperatures below 90 K. After thermal annealing in the O2 atmosphere, films showed zero resistivity at about 90 K.
