Lateral Jc distribution of YBCO coated conductors fabricated by IBAD/MOCVD process

The lateral J(c) distributions of YBCO coated conductors fabricated by IBAD/MOCVD process were measured by the magnetic knife method. In the samples, YBCO layer was deposited by MOCVD process on the IBAD template of GZO together with CeO2 layer. Ag-protective layer was put on YBCO layer. A series of voltage taps were attached with 10 mm separation, and the lateral Jc distribution was measured in each section between two voltage taps. A sample YBCO coated conductor in which YBCO layer was deposited five times using an up-to-date set-up shows a rather uniform J(c) distribution. The magnitude of J(c) reaches 2 x 10(10) A/m(2) (2 MA/cm(2)) in wide area of the conductor. (c) 2006 Published by Elsevier B.V.
