摘要：
Peculiar L-shaped diffuse streaks along <00 l>(pc) observed in (Na0.5Bio.5)TiO3 (NBT) below the Burns temperature, revealing the existence of polar nanoregions (PNRs). The displacement of Bi5+ cations is,-,0.26 A along <0 0 1>pc in the PNRs, with a size of l3 A in NBT. The BaTiO3 doping drives the diffuse scattering patterns to evolve from the L-shape into an ellipsoidal along <0 1 1 >pc in (Na0.5Bi0.5)TiO3 xBaTiO3. An abnormally large correlation length was observed in the morphotropic phase boundary composition with x = 0.05. (C) 2014 Acta Materialia Inc. Published by Elsevier Ltd. All rights reserved.
