Abstract
Processes for producing both the yttrium-stabilized zirconia (YSZ) template film by ion beam-assisted deposition (IBAD) and the YBa2Cu3Ox (YBCO) super conducting film by pulsed laser deposition (PLD) at 1-m lengths have achiev ed I-c values of 122 A and J(c) values of 1 MA/cm(2). Improvements have bee n 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 ca pability. The use of MgO as an IBAD template film has made great progress a nd can potentially decrease the time to produce the template film by more t han an order of magnitude. A combination of electrical and microstructural investigations is being made to understand and improve the properties of th e YBCO-coated conductors. (C) 2000 Elsevier Science B.V.
