Textured YBa2Cu3O7-x thick films (thickness ≈1 mm) were fabricated by vacuum filtration in an applied magnetic field (H=7 T). Platinum (1 wt %) was incorporated to induce liquid phase-assisted densification in films fired between 960 and 1030°C in oxygen. The transport critical current densities (Jct) of films fired to 1030°C exhibited nearly field insensitive behavior between H=0-3 T (H∥c-axis) at 77 K, with Jct≈2500A/cm2 and corresponding critical currents (Ic) of nearly 100 A at H=1 T.
