Diffraction investigations have been performed ojn poled 0.75Pb(Mg1/3Nb2/3)O3-0.25PbTiO3 crystals of cubic shape, where each cube face was oriented along a (001)-type plane. Contour small area reciprocal space scans of the three (001) faces of the cube were found to be in-equivalent. The results demonstrate a high micro-domain density within the poled condition, where micro-domain averagign produces monoclinic symmetry.
