Behavior of Optical Phonons near the Diffuse Phase Transition in Relaxor Ferroelectric PbMg1/3Ta2/3O3

S. G. Lushnikov, S. N. Gvasaliya, R. S. Katiyar

Raman scattering in relaxor ferroelectric PbMg1/3Ta2/3O3 (PMT) was investigated in the single crystalline form in the temperature range of 20 - 295 K. Anomalous temperature depende…

Dynamics of cubic-tetragonal phase transition in KNbO $_{3}$ perovskite

S. N. Gvasaliya, B. Roessli, R. A. Cowley +3

The low-energy part of the vibration spectrum in KNbO $_{3}$ was studied by cold neutron inelastic scattering in the cubic phase. In addition to acoustic phonons, we observe strong di…
