Abstract:

In this work, highly cube textured Ni-7at.%W (Ni7W) substrate was fabricated from the ingots synthesized by Spark Plasma Sintering (SPS) technique. Both the La2Zr2O7 (LZO) buffer layer and the YBCO superconducting layer were coated using chemical solution deposition (CSD) and pulsed laser deposition (PLO) layer by layer. The full-width-at-half-maximum (FWHM) values of the (1 1 1) phi-scan and the (2 0 0) omega-scan in rolling direction of the Ni7W substrate were 6.30 degrees and 5.08 degrees, respectively. The EBSD analyses indicated that the percentage of the cube texture component on the surface of the as-obtained Ni7W substrate was 99.4% within a tolerance angle of less than 10 degrees. Highly epitaxial growth of homogenous crack-free LZO film was obtained cube-on-cube relative to the Ni7W substrate, with FWHM values of (2 2 2) phi-scan and (4 0 0) omega-scan of 7.57 degrees and 5.73 degrees, respectively. The critical temperature of the YBCO layer prepared on LZO/Ni7 W substrate is about 90.5 K, while the critical current density is 1.25 MA cm(-2) (77 K, sf). (C) 2011 Published by Elsevier B.V.
