摘要：

The effects of annealing temperature and oxygen partial pressure [p(O2)] were investigated on the crystallization and orientation of superconducting YBa2Cu3O7-y (YBCO) films on SrTiO3(100) prepared by the dipping-pyrolysis process. Annealing conditions for precursor films consisting of a Y2O3-BaCO3-CUO mixture were varied in the temperature range 700-850-degrees-C and initial p(O2) range 2 x 10(-4)-10(-2) atm followed by pure O2 treatment. Three different types of crystallization behavior were observed. The c-axis-oriented epitaxial YBCO films were obtained on the lower p(O2) and higher temperature side in the p(O2)-T diagram. The c/a-axis-oriented growth was observed in films heat-treated at 750-800-degrees-C under p(O2) of 10(-3) atm. In addition, mixtures of YBCO and YBa2Cu4O8 resulted when the films were annealed at 700-degrees-C.
