Abstract

Tl_1-yBa₂Ca₂Cu₃O_x, y<0.2, (Tl-1223) films grown on polycrystalline yttria-stabilized zirconia (YSZ) substrates exhi bit a microstructure common in high-critical-current, high-temperature superconducting films. Plate-like grains are aligned with c-axes normal to the film; a- and b-axes are randomly oriented on a macroscopic scale. We describe X-ray pole-figure measurements from 0.1 mm regions of Tl-1223 films. For samples with the highest critical currents, the a-axes of the grains are locally aligned over distances up to 1 mm. Regions of higher critical current are associated with regions of high a-axis alignment.
