Notes:
Thin films of (001) YBCO are grown on epitaxially polished (001) MgO by pulsed organometallic beam epitaxy. The in-plane orientation of the film is controlled by the thickness of a BaO layer, grown in situ, prior to the YBCO growth. For thin BaO layers (〈≈7×1014 Ba/cm2) the films grown [110]YBCO(parallel)[100]MgO. For thick BaO layers ((approximately-greater-than)≈11×1014 Ba/cm2) the films grow [100]YBCO(parallel)[100]MgO. A mechanism that relates the change in YBCO in-plane orientation to a change in the structure of the initial BaO layers with BaO thickness is described. © 1996 American Institute of Physics.
