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…
Translational and rotational mode coupling in disordered ferroelectric KTa(1-x)Nb(x)O(3) studied by Raman spectroscopy
Oleksiy Svitelskiy, Jean Toulouse
The coupling of translational modes to the reorientational motion is an essential property of systems with internal orientational degrees of freedom. Due to their high complexity m…
