    • We present an investigation of the superconducting properties of thin YBa 2 Cu 3 O 7-x (YBCO) films grown on [001] single-crystalline quartz substrates by pulsed laser deposition (PLD) technique. The growth of YBCO on quartz is challenging due to large crystal lattice mismatch between YBCO and quartz. We obtained highly c-oriented textured films with superconducting transition at about 85 K, transition width of 1 K, and critical current density j c ≈ 10 4 A cm −2 at 77 K. Analysis of the temperature dependences of the resistivity and current-voltage characteristics has shown the presence of the thermally-assisted flux flow at temperatures above 70 K. From the temperature and magnetic field dependences of critical current, vortex activation energy, U 0 (H), was estimated for both parallel and perpendicular orientation of magnetic field. Second critical field, H c2 (0), was estimated from extrapolation of the H c2 (T) dependences. The obtained results are an important step towards realization of YBCO thin films on amorphous silica fibers for the third generation (3 G) of the HTS long wire with low losses in alternative current applications.

  • The physical basis of the fabrication of the third generation of high-temperature superconducting wires on quartz substrates
  • 2015
  • Ingår i: Moscow University Physics Bulletin (English Translation of Vestnik Moskovskogo Universiteta, Fizika). - 0027-1349 .- 1934-8460. ; 70:2, s. 134-139
  • Tidskriftsartikel (refereegranskat)abstract
    • The problem of the fabrication of third-generation high-temperature superconductors (HTSCs) that are designed for the transmission of electric energy and the creation of nanoelectronic devices is studied in this work. The issues of the fabrication of dielectric substrates for the third generation wires are considered. The technology of HTSC film deposition on the quartz substrates is presented. Complex studies of sputtering of the buffer and superconducting YBa2Cu3O7 − δ (YBCO) layers were performed. The results of studies of electrophysical properties of the HTSC films on the quartz substrates are discussed.
