Grain-aligned YBa2Cu3O7-x films were fabricated by vacuum filtration in an applied magnetic field (7 T). Platinum (Pt) was shown to lower the peritectic temperature of YBa2Cu 3O7-x by almost 75°C, leading to dramatic microstructural differences between films densified on MgO (single crystal) substrates and those densified on Pt foil to a maximum temperature of 1020°C in oxygen. Superconducting quantum-interference device hysteresis loops measured at 0-5.5 T at 5 K showed that films fired on Pt had ΔM (H app∥c axis) values 15-60 times larger than those fired on MgO.
