Abstract

The paper presents the current status of Ente per le Nuove tecnologie, ĽEnergia e ĽAmbiente research on the processing of high-irreversibility-field superconductor YBa2Cu3O7-x. (YBCO) tapes, useful for power application. A major part of this review is concerned with buffer layer growth, because this is the most important stage in the YBCO thick-film fabrication on biaxially textured metallic substrates. Several architectures are presented: CeO2/Pd/Ni, CeO2/(Ni-V) and CeO2/NiO/(Ni-V). For all the buffer layer structures the top CeO2 film was deposited by pulsed-laser deposition, while the Pd film was grown by electron-beam evaporation. The observed epitaxial orientation is [001]. The properties of a new non-magnetic Ni-V alloy substrate, as well as the preliminary results on superconducting multilayer structures, are also presented. The YBCO film grown on the CeO2/NiO/(Ni-V) configuration has the critical temperature Tc onset of 90.9 K, zero resistance at 86 K and the critical current density Jc = 105 Acrn−2 at 77 K and in zero magnetic field. © 2000 Taylor & Francis Group, LLC.
