Abstract: We report changes in the metric symmetry of unpoled and electrically poled single crystals of 0.26Pb(In1/2Nb1/2) O-3-0.46Pb(Mg1/3Nb2/3) O-3-0.28PbTiO(3), as revealed by neutron diffraction in conjunction with electrical measurements. The unpoled crystals show relaxor characteristics and an average rhombohedral symmetry that persists from ambient temperature up to the Curie temperature of similar to 165 degrees C. Poling along a [111] direction enhances the rhombohedral distortion away from cubic metric symmetry but appears not to induce any monoclinic phases. By contrast, the poled [001]-oriented crystal has orthorhombic (or monoclinic M-C) metric symmetry at 25 degrees C. An intermediate transition to a metrically tetragonal phase around 120 degrees C is confirmed for both poled crystals. © 2013, American Institute of Physics.
