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…

Clarification of size effects in polycrystalline BaTiO3 thin films by means of the specific heat measurements: grain size or film thickness?
B. A. Strukov, S. T. Davitadze, S. G. Shulman +2
Specific heat of polycrystalline BaTiO3 thin films on the fused quartz substrate was measured by ac-hot probe method. Phase transition temperature, excess entropy and spontaneous p…
