3-D mapping of diffuse scattering in PZN-xPT
Guangyong Xu, Z. Zhong, H. Hiraka +1
High energy (67 keV) x-ray diffuse scattering measurements were performed on single crystals of Pb(ZnNb)O-PbTiO (PZN-PT). A novel technique was develo…
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(…
Low symmetry phases in piezoelectric systems: PZN-xPT single crystal and powder
B. Noheda, D. E. Cox, G. Shirane
In this review we address some of the experimental challenges found in the x-ray diffraction characterization of the low-symmetry phases recently discovered in the PZT, PZN-PT and…
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…
