摘要：

We discuss our recent progress using IBAD MgO as a template for subsequent deposition of YBa2Cu3O7-delta (YBCO) high-temperature superconductors on metallic substrate tapes. We have refined the process by improving substrate preparation and by using reflected high-energy electron diffraction to monitor and improve IBAD MgO films. High quality, continuously processed IBAD MgO (c-IBAD) has been deposited on moving meter-length metal tape. By incorporating these optimized processing parameters, we have been able to deposit biaxially textured MgO on metallic substrates continuously with the best in-plane mosaic spreads near 9degrees. The subsequent pulsed laser deposition of 1-2 mum thick YBCO films on c-IBAD has resulted in superconducting transport critical current densities > 1 MA/cm(2) (75 K, SF) on small area samples. Longer 4.5 cm samples of c-IBAD tape have also been coated with a I cm wide sample carrying 93 A (75 K, SF) for a 1.5 mum thick YBCO. (C) 2002 Elsevier Science B.V. All rights reserved.
