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 [110]-oriented 0.7Pb(Mg1/3Nb2/3)O-3-0.3PbTiO(3) crystals have been investigated under uniaxial stress (sigma). [110]-oriented crystals have a longitudinal electromechanical coupling ...
Three intrinsic relationships of lattice parameters between intermediate monoclinic M-C and tetragonal phases in ferroelectric Pb (Mg1/3Nb2/3)(1-x)Ti-x O-3 and Pb (Zn1/3Nb2/3)(1-x)Ti-x O-3 near morphotropic phase boundaries
(American Physical Society, 2006-01-25)
Systematic analysis of extensive experimental data confirms the theoretical prediction of three intrinsic relationships of lattice parameters between the recently discovered intermediate monoclinic M-C phase and the ...
Importance of structural irregularity on dielectric loss in (1-x)Pb(Mg1/3Nb2/3)O-3-(x)PbTiO3 crystals
(AIP Publishing, 2002-06-01)
The dielectric properties of (1-x)Pb(Mg1/3Nb2/3)O-3-(x)PbTiO3 (PMN-PT) crystals have been investigated over a temperature range of 4 to 450 K at various frequencies. At low temperatures, an unusual frequency dependent ...
Damped soft phonons and diffuse scattering in 40%Pb(Mg1/3Nb2/3)O-3-60%PbTiO3
(American Physical Society, 2006-02-13)
Using neutron elastic and inelastic scattering and high-energy x-ray diffraction, we present a comparison of 40% Pb(Mg1/3Nb2/3)O-3-60% PbTiO3 (PMN-60PT) with pure Pb(Mg1/3Nb2/3)O-3 (PMN) and PbTiO3 (PT). We measure the ...
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 [111] 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 [111] applied electric field. Despite reports ...
