摘要：
YBa2Cu3Ox (YBCO) superconductors were coated on the CeO2/YSZ/Y2O3 buffered Ni5W tape by reel-to-reel pulsed laser deposition (PLD). To achieve high current carrying capacities, combinations of various deposition conditions were explored. X-ray diffraction measurements showed good in-plane and out-plane texture in YBCO films. The transition temperature of the coated YBCO was typically 89 K. The critical current is over 50 A at 77 K in meter-long YBCO tapes with a width of 1 cm. Their surface morphology was found being thickness-dependent. Further research work is under way.
