Quasi-Elastic Scattering, Random Fields and phonon-coupling effects in PbMg1/3Nb2/3O3
S N Gvasaliya, B Roessli, R A Cowley +2
The low-energy part of the vibration spectrum in PbMgNbO (PMN) relaxor ferroelectric has been studied by neutron scattering above and below the Burns temperatur…
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…
Neutron scattering study of PbMgTaO and BaMgTaO complex perovskites
S. N. Gvasaliya, B. Roessli, D. Sheptyakov +2
Neutron scattering investigations were carried out in PbMgTaO and BaMgTaO complex perovskites. The crystal structure of both compounds does…
Disorder and relaxation mode in the lattice dynamics of PbMgNbO relaxor ferroelectric
S. N. Gvasaliya, S. G. Lushnikov, B. Roessli
The low-energy part of vibration spectrum in PbMgNbO relaxor ferroelectric was studied by inelastic neutron scattering. We observed the coexistence of a resolut…
