Interplay between static and dynamic polar correlations in relaxor Pb(Mg1/3Nb2/3)O-3
(American Physical Society, 2010-04-01)
We have characterized the dynamics of the polar nanoregions in Pb(Mg1/3Nb2/3)O-3 through high-resolution neutron-backscattering and spin-echo measurements of the diffuse-scattering cross section. We find that the ...
Electroacoustic properties of < 110 >-oriented Pb-(Mg1/3Nb2/3)O-3-PbTiO3 crystals under uniaxial stress
(AIP Publishing, 2003-07-01)
The electromechanical properties of -oriented 0.7Pb(Mg1/3Nb2/3)O-3-0.3PbTiO(3) crystals have been investigated under uniaxial stress (sigma). -oriented crystals have a longitudinal electromechanical coupling ...
Evidence of decoupled lattice distortion and ferroelectric polarization in the relaxor system PMN-xPT
(American Physical Society, 2003-12-30)
We report high q-resolution neutron scattering data on PMN-xPT single crystals with x=20% and 27%. No rhombohedral distortion occurs in the 20PT sample for temperatures as low as 50 K. On the other hand, the 27PT sample ...
Neutron and x-ray diffraction study of cubic  field-cooled Pb(Mg1/3Nb2/3)O-3
(American Physical Society, 2007-08-01)
Neutron and x-ray diffraction techniques have been used to study the competing long- and short-range polar order in the relaxor ferroelectric Pb(Mg1/3Nb2/3)O-3 (PMN) under a  applied electric field. Despite reports ...
