Dynamic origin of the morphotropic phase boundary - Soft modes and phase instability in 0.68Pb(Mg1/3Nb2/3O3)-0.32PbTiO3
Hu Cao, Chris Stock, Guangyong Xu +3
We report neutron inelastic scattering on single crystal 0.68Pb(Mg1/3Nb2/3O3)-0.32PbTiO3 (PMN-0.32PT), a relaxor ferroelectric material that lies within the compositional range of…
The effect of local dipole moments on the structure and lattice dynamics of K0.98Li0.02TaO3
Jinsheng Wen, Guangyong Xu, C. Stock +5
We present high energy x-ray (67 keV) and neutron scattering measurements on a single crystal of KLiTaO for which the Li content () is less than $x_c = 0.02…
Response of polar nanoregions in 68%Pb(Mg1/3Nb2/3)O3-32%PbTiO3 to a [001] electric field
Jinsheng Wen, Guangyong Xu, C. Stock +1
We report neutron diffuse scattering measurements on a single crystal of 68%Pb(Mg1/3Nb2/3)O3-32%PbTiO3. Strong diffuse scattering is observed at low temperatures. An external field…
Phase instability induced by polar nanoregions in a relaxor ferroelectric system
Guangyong Xu, Jinsheng Wen, C. Stock +1
Local inhomogeneities known as polar nanoregions (PNR) play a key role in governing the dielectric properties of relaxor ferroelectrics - a special class of material that exhibits…
