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…

Structure and Dynamics of the Ferroelectric Relaxors Pb(Mg1/3Nb2/3)O3 and Pb(Zn1/3Nb2/3)O3
G. Shirane, P. M. Gehring
We review some of the current research on two of the ultra-high piezoelectric relaxors Pb(Mg1/3Nb2/3)O3 (PMN) and Pb(Zn1/3Nb2/3)O3 (PZN). The discovery of a monoclinic phase in Pb(…

Soft Phonon Anomalies in Relaxor Ferroelectrics
G. Shirane, P. M. Gehring
A review is given of the phonon anomalies, which have been termed ``waterfalls,'' that were recently discovered through a series of neutron inelastic scattering measurements on the…
