Abstract

We demonstrate that two distinctly different in-plane epitaxial states of c-axis oriented YBa₂Cu₃O_7-δ (YBCO) films on (100) yttria-stabilized ZrO₂ (YSZ) single-crystal substrates can be produced independently, namely, YBCO [100]//YSZ [100] or YBCO [100]//YSZ [110]. Both in-plane epitaxial relationships can be modeled by matching YBCO and YSZ oxygen sublattices at the film-substrate interface. High critical current densities (J_c), ∼5×10⁵-1×10⁶ A/cm² at 77 K, are achieved when ≳90 vol % of either orientation is present. J_c can be degraded nearly four orders of magnitude in films with mixed orientation.
