Abstract

We report on the effects of small miscuts of the (001) SrTiO₃ (STO) substrate surface, on the microstructure of epitaxial films of YBa₂Cu₃O_7-δ and NdBa₂Cu₃O_7-γ (NBCO). The most noticeable result is that, by growing NBCO films on miscut STO substrates with the steps intentionally oriented along a direction within 15° of [110], one reliably obtains NBCO films with a single [110] twinning variant (the [11¯0] is completely eliminated), which is a precious characteristic for all applications involving flux flow.
