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 ...
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 ...
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 ...
