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…

A study of the quantum classical crossover in the spin dynamics of the 2D S=5/2 antiferromagnet Rb2MnF4: neutron scattering, computer simulations, and analytic theories
T. Huberman, D. A. Tennant, R. A. Cowley +2
We report comprehensive inelastic neutron scattering measurements of the magnetic excitations in the 2D spin-5/2 Heisenberg antiferromagnet Rb2MnF4 as a function of temperature fro…

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…
