High-Tc Superconducting Films of Y-Ba-Cu Oxide Prepared by a CO2 Laser Beam Evaporation
Published online by Cambridge University Press: 28 February 2011
Abstract
The high-Tc YBCO superconducting films have been prepared using a cw CO2 laser evaporation from a single bulk target. The adjustment of the target composition, especially the yttrium concentration, was found to be a key factor to achieve a desired film composition. After post-annealing at 930°C, the films deposited on YSZ substrate exhibited a zero resistance temperature of 85K. The deposition rate of the films was about lOOA/sec.
