摘要：

NdGaO3 crystals are an excellent substrate material for epitaxial high-T(c) YBa2Cu3Ox (YBCO) films, but their application is restricted by their strong tendency towards twinning in the {112} and {110} planes. The mechanism of twinning was resolved. As a consequence, the formation of twins was reproducibly suppressed by the development of a modified growth technique.
