YBa{sub 2}Cu{sub 3}O{sub 7-{delta}} thick films on Ni-based alloys
- and others
YBa{sub 2}Cu{sub 3}O{sub 7-{delta}} (YBCO) thick films were prepared on Ni based alloys with an ion beam assisted deposited and textured yttria-stabilized zirconia (YSZ) buffer layer. Transport critical current densities (J{sub c}) over 1 {times} 10{sup 6} A/cm{sup 2} at 75 K, and over 1 {times} 10{sup 7} A/cm{sup 2} at 4 K were obtained in the 1 {mu}m thick YCBO films. Zero field critical current of 198 Amps at 75 K was obtained in a 2 {mu}m thick and 1 cm wide YBCO film. Angular dependence measurement revealed J{sub c} peaks for both H//c and H//a-b. The peak for H//c implies additional pinning due to defects such as small angle grain boundaries or twin boundaries. It was also found that the thick films on Ni based alloys were quite flexible.
