Abstract
High Jc YBCO thin film tapes were continuously fabricated on flexible Ni-based alloy. Biaxially aligned YBCO films were deposited by PLD on textured YSZ buffer layers formed by using IBAD (ion-beam-assisted deposition). For the short sample, Jc value of 1.13×106A/cm22 (77K, OT) was obtained and 1.1×105A/cm2 was maintained at 5T (Bic) with measured length of 1cm. For the long sample, Jc value of 2.1×105A/cm2, and Ic value of 20.8A were obtained (77K, OT) with measured length of 0.7m. Longitudinal uniformity of the long sample was excellent. Self-field a.c. losses of 0.25m length tapes were measured by a.c. four probe method. The results agreed with Norris’ prediction of low a.c. losses for thin strip conductors.
