Development of 500m-length IBAD-Gd2Zr2O7 film for Y-123 coated conductors

IBAD-Gd2Zr2O7 (GZO) film was fabricated on polycrystalline Ni-based alloy tape by the IBAD-system with 110cm×15cm ion source. Using long-length faraday-cup-array, effects of argon gas-flows on ion-current densities were investigated. As a result, lower gas-flow leads to higher ion-current density at...

Description
Summary:IBAD-Gd2Zr2O7 (GZO) film was fabricated on polycrystalline Ni-based alloy tape by the IBAD-system with 110cm×15cm ion source. Using long-length faraday-cup-array, effects of argon gas-flows on ion-current densities were investigated. As a result, lower gas-flow leads to higher ion-current density at the substrate in the system. Under the condition of low gas-flow, 10m (with production speed of 5m/h), 60m (3m/h) and 500m (5m/h)-length IBAD-GZO films were fabricated and their in-plane textures were Δϕ=15°, 13° and 18°, respectively. After that, PLD-CeO2 experiments were performed on the IBAD-GZO substrates with Δϕ=15° and 13°, and then CeO2 films with Δϕ=5.5° and 5.7° were achieved with the tape-speed of 5.0m/h and 10.0m/h, respectively.
