Soft Modes and Relaxor Ferroelectrics
R. A. Cowley, S. N. Gvasaliya, B. Roessli
Relaxor ferroelectrics are difficult to study and understand. The experiment shows that at low energy scattering there is an acoustic mode, an optic mode, dynamic quasi-elastic sca…

Dynamics of cubic-tetragonal phase transition in KNbO perovskite
S. N. Gvasaliya, B. Roessli, R. A. Cowley +3
The low-energy part of the vibration spectrum in KNbO was studied by cold neutron inelastic scattering in the cubic phase. In addition to acoustic phonons, we observe strong di…
