摘要
The Ag clad tape consisting of Ag-0.1%Cu and some Ni alloys was prepared. The textured property, the proof stress at high temperature and the superconductivity of YBa2Cu3 (YBCO) film deposited by PLD were studied. The uniform clad tape with a length of 10 m and a thickness of 0.1 nun was obtained and it showed the textured structure of (210)(120) after annealing at 700 degreesC. YBCO filmdeposited on the textured clad tape was aligned in-plane. From two to four times higher proof stress sigma (0.2) at 700 degreesC than that of Ag was obtained by cladding. High J(c) value of about 10(5) A/cm(2) was obtained on Ag-0.1%Cu/Ag-10%Ni clad tape. (C) 2001 Elsevier Science B.V. All rights reserved.
