【 摘 要 】

HTSC 2G YBCO based short samples were formed by PLD (pulsed laser deposition) on the cube textured Ni-W tapes. The influence of buffer layer architecture on the critical properties of HTS films was investigated with scanning and transmission electron microscopy, X-ray diffraction and four point probe electrical measurement. The best critical properties were found in the HTS grown on tapes with triple buffer layers: Y2O3, YSZ and CeO2. After CeO2layer deposition the blister-like defects appeared on the buffers surface. These defects being inherited by YBCO film could lead to degradation of critical properties.
