Coexistence and competition of local- and long-range polar orders in a ferroelectric relaxor
Guangyong Xu, P. M. Gehring, G. Shirane
We have performed a series of neutron diffuse scattering measurements on a single crystal of the solid solution Pb(ZnNb)O (PZN) doped with 8% PbTiO (PT), a…
Inelastic neutron scattering study of phonons and magnetic excitations in LaCoO
Y. Kobayashi, Thant Sin Naing, M. Suzuki +7
We have investigated the phonon and the magnetic excitations in LaCoO3 by inelastic neutron scattering measurements. The acoustic phonon dispersions show some characteristic featur…
Structural phase transition and dielectric relaxation in Pb(Zn1/3Nb2/3)O3 single crystals
Y. -H. Bing, A. A. Bokov, Z. -G. Ye +2
The structure and the dielectric properties of Pb(Zn1/3Nb2/3)O3 (PZN) crystal have been investigated by means of high-resolution synchrotron x-ray diffraction (with an x-ray energy…
Cold neutron scattering study on diffuse and phonon excitations in the relaxor PbMg(1/3)Nb(2/3)O3
H. Hiraka, S. -H. Lee, P. M. Gehring +2
Cold neutron scattering experiments have been performed to explore the energy, temperature, and wave-vector dependence of the diffuse scattering and the transverse acoustic (TA) ph…
X-ray and Neutron Diffraction Investigations of the Structural Phase Transformation Sequence under Electric Field in 0.7Pb(Mg1/3Nb2/3)-0.3PbTiO3 Crystals
Feiming Bai, Naigang Wang, Jiefang Li +4
The structural phase transformations of 0.7Pb(Mg1/3Nb2/3)O3-0.3PbTiO3 (PMN-30%PT) have been studied using x-ray diffraction (XRD) and neutron scattering as a function of temperatur…
High q-resolution neutron scattering technique using triple-axis spectrometers
Guangyong Xu, P. M. Gehring, V. J. Ghosh +1
We present a new technique which brings a substantial increase of the wave-vector -resolution of triple-axis-spectrometers by matching the measurement wave-vector to the ref…
