Abstract

The effect of thermal annealing on the boundary chemistry of Tl-1223 compounds (Tl_xBa₂Ca₂Cu₃O_y) is studied. Results reveal that the enhancement of J_c in Tl-1223 films does not result from improvement of the properties of twist grain boundaries. The microstructure has been shown from X-ray diffraction and electron back-scattering diffraction studies to consist of colonies of grains with similar but not identical basal plane orientations, and it has been suggested that long-range conduction occurs through a percolative network of small-angle tilt boundaries at colony intersections.
