Title
Mesoseopic ordering in the 0.9 $Pb(Mg_{1/3}Nb_{2/3})O_{3}-0.1$ $PbTiO_{3}$ relaxor ferroelectric : a HRTEM study

Abstract
 We report a microstructural and compositional study of a 90% Pb(Mg1/3Nb2/3)O-3 - 10% PbTiO3 ceramic sample. High resolution transmission electron microscopy (HRTEM) revealed the presence of compositional ordered nano-domains (1 - 4 mn), observable in two specific orientations, [0 (1) over bar 1] and [1 1 (2) over bar]. However, the visibility and the ordering degree of the nano-domains on the HRTEM images are not at all obvious. Fourier filtering of the images clearly revealed the ordered domains. Antiphase boundaries lying in the (111) planes separate them, while (100) and (111) facets separate the ordered domains from the disordered matrix. Their shape is plate-like, not uniformly spread in the disordered matrix. Their average size varies in different regions of the sample, most probably due to a non-uniform distribution of Ti, as observed by energy dispersive X-ray spectroscopy.
