The not so simple cubic structure of PbZr 1-x Ti xO 3 (PZT): Complex local structural effects in perov-skites

Acta Crystallographica Section B: Structural Science 67:6 (2011) 461-466

Authors:

N Zhang, H Yokota, AM Glazer, PA Thomas

Abstract:

High-resolution neutron diffraction on the important piezoelectric lead zirconate titanate (PZT) has found that oxygen disorder exists well into the cubic phase. This unexpected result shows that within this phase there persists a remnant of the tilted oxygen octahedra present within the room-temperature ferroelectric phase. The result is that the cubic phase, far from having a simple crystal structure, exhibits a more complex local structure than had hitherto been thought. © 2011 International Union of Crystallography Printed in Singapore - all rights reserved.
