Inclined-substrate deposition of biaxially aligned template films for YBCO-coated conductors.
Abstract
Inclined-substrate deposition (ISD) of magnesium oxide (MgO) produces biaxially textured template films at high deposition rates. This process is promising for the fabrication of the second-generation superconducting wires. Biaxially aligned MgO films ({approx}1.5 {mu}m thick) were deposited on polished Hastelloy C276 (HC) substrates by ISD at deposition rates of 20-100 {angstrom}/s. Buffer films were subsequently deposited on these template films, and YBCO films were deposited epitaxially on the substrates by pulsed laser deposition. X-ray pole figure analysis and {psi}- and {omega}-scans were used for texture characterization. Good in- and out-of-plane textures were observed, with MgO(0 0 2) {phi}-scan full-width at half maximum (FWHM) of 9.2{sup o} and {omega}-scan FWHM of 5.4{sup o}, respectively. T{sub c} of 90 K with a sharp transition, and J{sub c} {approx} 2 x 10{sup 5} A/cm{sup 2}, were obtained on a 0.5 {mu}m thick, 0.5 cm wide, and 1 cm long YBa{sub 2}Cu{sub 3}O{sub 7-{delta}} (YBCO) film at 77 K in self-field.
