A Neutron Elastic Diffuse Scattering Study of PMN
Guangyong Xu, G. Shirane, J. R. D. Copley +1
We have performed elastic diffuse neutron scattering studies on the relaxor Pb(MgNb)O (PMN). The measured intensity distribution near a (100) Bragg peak in the…
Electric Field Effects on the Diffuse Scattering in PZN-8%PT
P. M. Gehring, K. Ohwada, G. Shirane
We report measurements of the neutron diffuse scattering from a single crystal of the relaxor ferroelectric Pb(Zn_1/3Nb_2/3)O_3 doped with 8% PbTiO_3 (PZN-8%PT) for temperatures 10…
Evidence of decoupled lattice distortion and ferroelectric polarization in the relaxor system PMN-xPT
Guangyong Xu, D. Viehland, J. F. Li +2
We report high -resolution neutron scattering data on PMN-PT single crystals with and 27%. No rhombohedral distortion occurs in the 20PT sample for temperatures as lo…
Dynamics and Structure of PMN and PZN
G. Shirane, Guangyong Xu, P. M. Gehring
A review is given of recent neutron and x-ray scattering studies of the lead-oxide perovskite relaxor systems Pb(Zn1/3Nb2/3)O3-xPbTiO3 and Pb(Mg1/3Nb2/3)O3-xPbTiO3. X-ray measureme…
A Universal Phase Diagram for PMN-xPT and PZN-xPT
P. M. Gehring, W. Chen, Z. -G. Ye +1
The phase diagram of the Pb(Mg1/3Nb2/3)O3 and PbTiO3 solid solution (PMN-xPT) indicates a rhombohedral ground state for x < 0.32. X-ray powder measurements by Dkhil et al. show a r…
