摘要：

High JcY1Ba2CU3O7-x superconducting thin and thick films were prepared onto SrTiO3 (100) substrates at 700-degrees-C by metalorganic chemical vapor deposition (MOCVD) technique using a single solution source. A mixture of Y, Ba, and Cu beta-diketonate chelates was dissolved in tetrahydrofuran as a solution source. Zero resistance transition temperature and critical current density at 77 K, 0 T for thin and thick films were 90 K and 2.73 X 10(6) A/cm2, 91 K and 3.1 X 10(5) A/cm2, respectively. X-ray diffraction measurement indicated that the thin film grew epitaxially with the c-axis orientation perpendicular to the surface of the substrate and the thick films mainly consisted of a-axis orientation.
