Textured YBa2Cu3O7-x films (thickness = 250 μm) 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 935 - 942°C under reduced pO2(g) conditions. The transport critical current densities (Jet) of such films exhibited nearly field insensitive behavior between H = 0-3 T (H II c-axis) at 77 K, with Jct > 1000 A/cm2 ut H = 0 T.
