Abstract
High temperature superconducting thin film tapes, which consist of a flexib le metal substrate, buffer layer, and Y1Ba2Cu3Ox, (YBCO) layer have been de veloped for power application. Ni-alloy tape was used as the substrate. Bot h the YBCO layer and the buffer layer were formed by pulsed laser depositio n (PLD) because of an advantageous of high deposition rate. Inclined substr ate deposition (ISD) was developed to introduce in-plane alignment for the buffer layer on the non-textured metal substrate. YBCO films epitaxially de posited on the ISD buffer layer by normal PLD had high J(c) values over 10( 5) A/cm(2) at 77 K. For verification of high rate productivity of the PLD/I SD method, we demonstrated high rate deposition of the yttria stabilized zi rconia buffer layer and YBCO superconducting layer. We also performed conti nuous deposition of over 10 m YBCO thin film tapes with a reel-to-reel subs trate transfer system combined with 200 W high power laser equipment.
