In-plane oriented a-axis heteroepitaxial multilayers consisting of YBa2Cu3O7−x/PrBa2Cu3O7−y bilayers and insulating LaSrGaO4 and Nd2CuO4 on (100) LaSrGaO4 substrates have been fabricated. φ-scan measurements of reflections from (101) Nd2CuO4 and (102) YBa2Cu3O7−x planes display twofold symmetry, indicating in-plane oriented growth of the top and middle layers in superconductor-insulator-superconductor structures for an insulating barrier thickness of 3000 A(ring). For structures with a Nd2CuO4 barrier, both top and bottom layers had Tc(R=0)≥85 K. © 1995 American Institute of Physics.
