摘要：

GdBa2Cu3Oy (GdBCO) films have been prepared on UAlO3 single-crystal Substrates by metal-organic deposition (MOD) using new fluorine-free complex solutions consisting of metal 2-ethylhexanates (2-EH) and metal naphthenates. The dispersion of T-c values for GdBCO films improved by using a complex solution, rather than only a solution of metal naphthenates. c-axis oriented GdBCO films with flat surfaces were grown under lower calcining temperatures and higher firing temperatures than in the process using only metal naphthenates. The T-c and J(c), of the GdBCO films were 91.2 K and 0.61 MA/cm(2), respectively, at 77 K at self-field. (c) 2008 Elsevier B.V. All rights reserved.
