Abstract

The influence of (Y_0.8Ca_0.2)Ba₂Cu ₃O_y (YCBCO) over-layers on YBCO film properties has been studied on multi-layer YBCO/YCBCO films. The films were deposited on (001) MgO single-crystal substrates by pulsed-laser deposition. The results unambiguously demonstrate that a YCBCO over-layer can greatly improve the overall crystallinity of the YBCO films and thus their J_c. An optimal layer-number (n) of the multi-layer YBCO (n layers)/YCBCO (n-1 layers) has been identified to produce a maximum J_c enhancement. The observations suggest that the YBCO/YCBCO multi-layer healing technique (MLHT) mentioned above may be used for the fabrication of low cost, high performance YBCO coated conductors by relaxing the stringent and costly requirements for precise atomic alignment employed in previous fabrication methods.
