Detailed x-ray scattering measurements in three dimensions are reported for thin YBa/sub 2/Cu/sub 3/O/sub /ital x// films on (001) SrTiO/sub 3/ and KTaO/sub 3/ substrates. The films, produced by coevaporation followed by a postdeposition anneal, consist of domains epitaxially oriented with either the /ital a/ axis or the /ital c/ axis aligned with the substrate normal. The in-plane epitaxy of grains with the /ital c/ axis parallel to the normal shows an alignment of the <110> directions of the film and the substrate, rather than of the <100> directions as is generally presumed. We associate this alignment with a strain relaxation during the high-temperature tetragonal-to-orthorhombic phase transition.
