Long length fabrication of YBCO on rolling assisted biaxially textured substrates (RABiTS) using pulsed laser deposition

The continuous deposition of multilayer oxide films on moving long-length metallic substrates using pulsed laser deposition (PLD) is reported. Epitaxial YBCO/CeO2/yttria-stabilized zirconia (YSZ)/CeO2 layers were grown on 1cm X 10cm rolled-Ni tape substrates. The Ni tape was heated radiatively and translated while oxide layers were continuously deposited, The thickness and composition along the moving direction were to within +/-7% and +/-5%, respectively. The biaxial texture of the 10cm Ni tape was transferred through the buffer lavers to the topmost YBCO during the continuous deposition. The in-plane and out-of-plane texturing of YBCO and buffer layers were uniform along the scanning direction with variations less than +/-10% and +/-5%, respectively, The average transport zero field J(c) (77K) for numerous 10 cm samples was about 200,000 A/cm(2), with the highest J(c) and I-c values at 77K, 0T of 270,000 A/cm(2) and 16.7 ii respectively. This study demonstrates the feasibility of continuous multilayer, multi-component oxide film deposition on rolled-textured metal with uniform thickness, composition, and crystallographic orientation using PLD.
