Abstract

Textured YBa₂Cu₃O_7-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 942°C under reduced pO2(g) conditions. The transport critical current densities (Jct) of such films exhibited nearly field insensitive behavior between H = 0-3 T (H || c-axis) at 77 K, with J_ct > 1000 A/cm² at H = 3 T.
