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…
Anomalous transverse acoustic phonon broadening in the relaxor ferroelectric Pb(Mg_1/3Nb_2/3)O_3
T. -Y. Koo, P. M. Gehring, G. Shirane +3
The intrinsic linewidth of the transverse acoustic (TA) phonon observed in the relaxor ferroelectric compound Pb(MgNbTiO (PMN-20%PT) beg…
A first-principles study of the structure and lattice dielectric response of CaCu{3}Ti{4}O{12}
Lixin He, J. B. Neaton, Morrel H. Cohen +2
Structural and electronic properties of CaCu{3}Ti{4}O{12} have been calculated using density-functional theory within the local spin-density approximation. After an analysis of str…
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…
Neutron Diffuse Scattering from Polar Nanoregions in the Relaxor Pb(Mg1/3Nb2/3)O3
K. Hirota, Z. -G. Ye, S. Wakimoto +2
We have studied the neutron diffuse scattering in the relaxor PMN. The diffuse scattering appears around the Burns temperature (~620K), indicating its origin from the polar nanoreg…
Phase diagram of the relaxor ferroelectric (1-x)PbZn(1/3)Nb(2/3)O3-xPbTiO3
D. La-Orauttapong, B. Noheda, Z. -G. Ye +4
Recently, a new orthorhombic phase has been discovered in the ferroelectric system Pb(Zn1/3Nb2/3)O3-xPbTiO3 (PZN-xPT) for x= 9%, and for x= 8% after the application of an electric…
