摘要
YBCO thin films were deposited by pulsed laser deposition from targets fabricated using the modified melt-textured growth (MTG) method and the solid-state sintering (SSS) method. All of the films showed c-axis orientations, but the films from the MTG targets had better crystallinity than those from the SSS targets. As the substrate temperature was increased, T-c and J(c) of the films increased. The films from the MTG targets showed better superconducting properties than those from the SSS targets. From the composition analysis of the targets, the Y-richer vapor species arriving at the substrate from the MTG targets are thought to form a thermodynamically more stable YBCO phase with less cation disorder.
