Electric-field induced phase transitions in rhombohedral PZN-xPT
B. Noheda, Z. Zhong, D. E. Cox +3
High-energy x-ray diffraction experiments peformed on rhombohedral (1-x)Pb(Zn1/3Nb2/3)O3-xPbTiO3(PZN-xPT) crystals with x= 4.5 and 8% show that an electric field applied along the…
Neutron Diffraction Study of the Irreversible R-MA-MC Phase Transition in Single Crystal Pb[(Zn1/3Nb2/3)1-xTix]O3
Kenji Ohwada, Kazuma Hirota, Paul W. Rehrig +5
Single crystals of the relaxor PZN-xPT display an enormously strong piezoelectric character. Recent x-ray scattering studies have revealed novel electric-field induced phase transi…
Dynamical effects of the nanometer-sized polarized domains in Pb(Zn1/3Nb2/3)O3
P. M. Gehring, S. -E. Park, G. Shirane
Recent neutron scattering measurements performed on the relaxor ferroelectric Pb[(Zn1/3Nb2/3)0.92Ti0.08]O3 (PZN-8%PT) in its cubic phase at 500 K, have revealed an anomalous ridge…
Polarization rotation via a monoclinic phase in the piezoelectric 92%PbZn1/3Nb2/3O3-8%PbTiO3
B. Noheda, D. E. Cox, G. Shirane +3
The origin of ultrahigh piezoelectricity in the relaxor ferroelectric PbZn1/3Nb2/3O3-PbTiO3 was studied with an electric field applied along the [001] direction. The zero-field rho…
The monoclinic phase in PZT: new light on morphotropic phase boundaries
B. Noheda, J. A. Gonzalo, R. Guo +4
A summary of the work recently carried out on the morphotropic phase boundary (MPB) of PZT is presented. By means of x-ray powder diffraction on ceramic samples of excellent qualit…
Soft Phonon Anomalies in the Relaxor Ferroelectric Pb(Zn_1/3Nb_2/3)_0.92Ti_0.08O_3
P. M. Gehring, S. E. Park, G. Shirane
Neutron inelastic scattering measurements of the polar TO phonon mode dispersion in the cubic relaxor Pb(Zn_1/3Nb_2/3)_0.92Ti_0.08O_3 at 500K reveal anomalous behavior in which the…
