Deposition and characterization of YBCO/CeO2 thin films prepared by thermal co-evaporation on metallic tapes

A market penetration of HTS-based applications requires the development of a low-cost continuous production system for long HTS conductors. We report on deposition and characterization of YBa2Cu3O7-delta/CeO2 structures on metallic substrates prepared by a thermal co-evaporation technique: X-ray diffraction analysis reveals good biaxial orientation of both layers with in- and out-of-plane FWHM = 8degrees and 9degrees respectively on biaxially textured Ni-Fe or Ni-W and on polycrystalline Hastelloy C276 substrates. YBCO films are metallic and superconducting with T-c,T-onset similar to 88 K. Work is in progress to scale up the process for long tapes.
