Textured YBa2Cu3O7−xthick 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 betweenH=0–3 T (H∥c‐axis) at 77 K, withJct≊2500 A/cm2and corresponding critical currents (Ic) of nearly 100 A atH=1 T. ©1995 American Institute of Physics.
