Neutron inelastic scattering measurements of low energy phonons in the multiferroic BiFeO3
John A. Schneeloch, Zhijun Xu Jinsheng Wen, P. M. Gehring +11
We present neutron inelastic scattering measurements of the low-energy phonons in single crystal BiFeO3. The dispersions of the three acoustic phonon modes (LA along [100], TA1 alo…
Freezing of the local dynamics in the relaxor ferroelectric PZN-4.5PT
Zhijun Xu, Jinsheng Wen, E. Mamontov +3
We report measurements of the neutron diffuse scattering in a single crystal of the relaxor ferroelectric material 95.5%Pb(Zn1/3Nb2/3)O3-4.5%PbTiO3 (PZN-4.5%PT). We show that the d…
A two-component model of the neutron diffuse scattering in the relaxor ferroelectric PZN-4.5%PT
Zhijun Xu, Jinsheng Wen, Guangyong Xu +3
We report measurements of the neutron diffuse scattering in a single crystal of the relaxor ferroelectric material 95.5%Pb(ZnNb)O-4.5%PbTiO (PZN-4.5%PT). Ou…
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…
Mode-coupling and polar nanoregions in the relaxor ferroelectric Pb(Mg1/3Nb2/3)O3
S. Wakimoto, C. Stock, Z. -G. Ye +3
We present a quantitative analysis of the phonon lineshapes obtained by neutron inelastic scattering methods in the relaxor ferroelectric Pb(Mg1/3Nb2/3)O3 (PMN). Differences in the…
Ferroelectric Ordering in the Relaxor Pb(Mg1/3Nb2/3)O3 as Evidenced by Low-Temperature Phonon Anomalies
S. Wakimoto, C. Stock, R. J. Birgeneau +5
Neutron scattering measurements of the lowest-energy TO phonons in the relaxor Pb(Mg1/3Nb2/3)O3 (PMN) are reported for 10<=T<=750 K. The soft mode, which is overdamped by the polar…
