Abstract

Using photolithography, links for transport measurement have been placed across individual Ni grain boundaries and within individual Ni grains on several coated conductor samples. The typical Ni grain size is ∼50 μm, while the YBa₂Cu₃O_7-x grains are submicron in size. It is found that the intragrain J_c(0 T,77 K) can exceed 5 MA/cm², thus showing that present coated conductor J_c values are not significantly limited by the intragrain J_c. Inter- and intragrain J_c values ranged from one-half to more than four times full-width measured values, demonstrating that current percolates through the conductor. The misorientation angle dependence of J_c fits well with previous studies of [001] tilt SrTiO₃ bicrystals.
