Abstract
High Jc Y1Ba2Cu3O7−x superconducting thin and thick films were prepared onto SrTiO3 (100) substrates at 700 °C by metalorganic chemical vapor deposition (MOCVD) technique using a single solution source. A mixture of Y, Ba, and Cu β‐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 2.73×106 A/cm2, 91 K and 3.1×105 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.Keywords
