Abstract
E-J characteristics in a YBCO coated conductor at low temperature and very high magnetic field up to 27 T have been estimated using experimental E-J characteristics below 12 T along with a scaling analysis based on the percolation model. 1 mm thick YBCO films was deposited on a biaxially aligned Y2O3/YSZ/Hastelloy substrate fabricated by the IBAD technique. The critical current Ic for the 1 cm wide tape was 85 A at 77 K in self-field. We measured E-J characteristics in perpendicular field up to 12 T using 100 μm wide and 1 mm long bridge patterned in the tape. Statistic Jc distribution and pinning properties were analyzed from the E-J characteristics. Using the pinning parameters determined by the scaling analysis, we can calculate the critical current properties as a function of temperature and magnetic field. E-J characteristics at low temperature and very high magnetic field up to 27 T were estimated analytically and compared with the experimental data. Estimated value of Jc and n-value, and their error analysis were also discussed.
