Abstract

Anisotropie surface texturing of the polycrystalline yttria-stabilized zirconia substrates, prior to YBa2Cu3O7−x film deposition, is shown to promote in-plane (basal plane) ordering of the film growth in addition to thec-axis texturing. TheJ c 's of the films in the weak-link-dominated low-field regime are enhanced considerably, and this result is attributed to the reduction of weak links resulting from a reduction in the number of in-plane large-angle grain boundaries.
