摘要

Processes for producing both the yttrium-stabilized zirconia (YSZ) template film by ion beam-assisted deposition (IBAD) and the YBa2Cu3Ox (YBCO) superconducting film by pulsed laser deposition (PLD) at 1-m lengths have achieved I-c values of 122 A and J(c) values of 1 MA/cm(2). Improvements have been made in all stages of the process. Variations of I-c along the length of the 1-m samples stimulated development of a new in-field I-c measurement capability. The use of MgO as an IBAD template film has made great progress and can potentially decrease the time to produce the template film by more than an order of magnitude. A combination of electrical and microstructural investigations is being made to understand and improve the properties of the YBCO-coated conductors. (C) 2000 Elsevier Science B.V.
