Piezoelectric Polar Nano Regions and Relaxation-Coupled Resonances in Relaxor Ferroelectrics
Ling Cai, Radha Pattnaik, Joel Lundeen +1
\indent It is a generally accepted fact that the unique dielectric properties of relaxor ferroelectrics are related to the formation of polar nanoregion (PNRs). Less well recognize…
Resonance Damping of the THz-frequency Transverse Acoustic Phonon in the Relaxor Ferroelectric KTa1-xNbxO3
J. Toulouse, E. Iolin, B. Hennion +2
The damping () of the transverse acoustic (TA) phonon in single crystals of the relaxor with x=0.15-0.17 was studied by means of high resolution inelastic c…
Theoretical Study of the Soft Optic Mode Dynamics in a Relaxor Ferroelectric. The Effect of Polar Nanoregions
E. Iolin, J. Toulouse
We propose a simple and solvable mean-field model of the scattering of transverse optic modes by Polarized Nano Regions (PNR) in the paraelectric phase of relaxor ferroelectrics. T…
Raman spectroscopy study of internal dynamics in Pb(Zn_{1/3}Nb_{2/3})O_{3} and 95.55%Pb(Zn_{1/3}Nb_{2/3})O_{3}-4.5%PbTiO_{3} crystals
O. Svitelskiy, D. La-Orauttapong, J. Toulouse +2
Pb(ZnNb)O is one of the simplest representatives of the lead ferroelectric relaxors. Its solid solution with PbTiO, at concentrations near the morphotro…
Condensation and Slow Dynamics of Polar Nanoregions in Lead Relaxors
D. La-Orauttapong, O. Svitelskiy, J. Toulouse
It is now well established that the unique properties of relaxor ferroelectrics are due to the presence of polar nanoregions (PNR's). We present recent results from Neutron and Ram…
Polarized Raman study of the phonon dynamics in Pb(MgNb)O crystal
Oleksiy Svitelskiy, Jean Toulouse, Z. -G. Ye
Pb(MgNb)O is one of the simplest representatives of the class of lead relaxors and often serves as a model system for more complicated compounds. In this pape…
