Abstract

GdBa2Cu3Oy (GdBCO) films have been prepared on LaAlO3 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 Tc 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 Tc and Jc of the GdBCO films were 91.2 K and 0.61 MA/cm2, respectively, at 77 K at self-field.
