Observation of domain texture in poled Pb(Mg1/3Nb2/3)O-3-PbTiO3 crystals

Mapping of domain distributions under constant Bragg conditions has been performed on poled (0.7)Pb(Mg1/3Nb2/3)O-3-0.3PbTiO(3) crystals. Studies were done on crystals of cubic geometry, where each cube face was oriented along a 001. Multiple domains with monoclinic limiting symmetry (angle similar to173degrees-176degrees) were observed on all three (001)(c) faces. Perpendicular to the poling direction, domain modulations were observed by a splitting of each variant. (C) 2002 American Institute of Physics.
