双轴织构金属基带上沉积YBCO高温超导膜的研究

摘要

制备了立方织构和｛110｝双轴织构的银基带，通过准分子激光方法在所制备的双轴织构的银基带上直接沉积了YBCO超导薄膜，其中在｛110｝双轴织构的银基带上沉积的超导薄膜的临界电流密度Ju001bCu001b值达到2×105～5×105A／cm5(77K，0T)．%Cube textured and ｛110｝<211>textured silver tapes were prepared. YBCO films were deposited on biaxially textured Ag tapes directly. Experiments show that ｛110｝ biaxially textured Ag tape is fitted for the deposition of YBCO films. The transport current measured for the film is 4×105u001bA/cm2u001bat 77K, 0T．
