Abstract

Textured YBa₂Cu₃O_7−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 (J_ct) of films fired to 1030 °C exhibited nearly field insensitive behavior between H=0–3 T (H∥c‐axis) at 77 K, with J_ct≊2500 A/cm² and corresponding critical currents (I_c) of nearly 100 A at H=1 T.
