摘要：

Textured YBa2Cu3O7-x films (thickness approximate to 250 mu m) were fabricated by tape casting in an applied magnetic field (H = 6 T). Platinum (1 wt%) was incorporated to induce liquid phase-assisted densification in films fired on silver (Ag) foil to 942 degrees C under reduced pO(2)(g) conditions. The transport critical current densities (Jct) of such films exhibited nearly field insensitive behavior between H = 0-3 T (H parallel to c-axis) at 77 K, with J(ct) > 1000 A/cm(2) at H = 3 T.
