We report the formation of biaxially oriented films of yttorium-stabilized ZrO2 (YSZ) on a poly-crystalline, Ni-based alloy (Hastelloy c276) by Ion-Beam-Assisted Deposition (IBAD), and the subsequent a-b plane aligned YBa2Cu3O7-x (YBCO) films deposited by laser ablation. Jc of 6.0 x 104 A/cm2 (77 K, O T) and 1.4 x 104 A/cm2 (77 K, 0.6 T) were obtained. A new method to prevent intergranular-weak-links has been developed for application of oxide superconducting thin films, for tape-shaped cables, magnets, magnetic shields, microwave devices, etc.
