摘要：

We report a successful fabrication of high-J(c) GdBa2Cu3O7-delta (GdBCO) films by the metal-organic deposition process on the LaAlO3 (LAO) (0 0 1) substrates. The coating solution was prepared by mixing Gd, Cu fluorine-free sources with Ba trifluoroacetate. Samples were dip-coated, pyrolized within 3 h at the temperature up to 400 degrees C in a humid oxygen atmosphere, and finally fired at various high temperatures in 100 ppm Ar/O-2 atmosphere. The GdBCO films fired at 775 and 800 C exhibited J(c), values of similar to 2.1 MA/cm(2) at 77 K in a self-field, which are attributable to both high T-c.zero values of similar to 89 K and high in-plane textures of 1.3-1.4 degrees. Above 800 degrees C, however, the superconducting properties of GdBCO films are degraded due to the thermal decomposition of GdBCO film in 100 ppm Ar/O-2 atmosphere.
