摘要：

YBa2Cu3O7-delta (YBCO) superconductors were coated on the CeO2/YSZ/Y2O3 buffered Ni-5at%W tapes by a reel-to-reel pulsed laser deposition (PLO). The process of a multi-layer deposition of YBCO film was explored. X-ray diffraction texture measurements showed good both in-plane and out of plane crystalline orientations in YBCO films. The average values calculated at a full width at half maximum (FWHM) of the peaks from phi-scans (phi) and omega (omega) scans for one meter-long YBCO tape were 7.49 degrees and 4.71 degrees, respectively. The critical current (I-c) was over 200 A/cm-width at 77 K and under self-field for meter-long YBCO tape. The critical transition temperature of the YBCO tape was typically as 901 K with 0.5 K transition widths. (C) 2011 Elsevier B.V. All rights reserved.
