Abstract
Non-c-axis oriented epitaxial films of bismuth layer-structured ferroelectr ics, SrBi2Ta2O9 (SBT) and SrBi2Nb2O9 (SBN), were prepared on SrTiO3(110) by coating-pyrolysis process. These films were found to be (106)-oriented (ps eudo-tetragonal indices). interestingly, this orientation is 'stealthy' or unseen in the conventional XRD theta-2 theta scans due to extinction rule s o that its presence was revealed by XRD pole-figure measurement and recipro cal-space mapping. The crystallographic relationship of the films and subst rates was SBT, SBN (106) parallel to SrTiO3 (110) and SBT, SBN [010] parall el to SrTiO3 [001]. This epitaxial relationship was also discussed from the standpoint of ion arrangement. (C) 1999 Elsevier Science S.A. All rights r eserved.
