Excitations in a thin liquid 4He film from inelastic neutron scattering.
We perform a thorough analysis of the experimental dynamic structure function measured by inelastic neutron scattering for a low-temperature (T50.65 K! four-layer liquid He film. The results are interpreted in light of recent theoretical calculations of the ~nonvortex! excitations in thin liquid Bose films. The experimental system consists of four outer liquid layers, adsorbed to two solid inne...
متن کاملLow-energy excitations and the fast process of polystyrene thin supported films studied by inelastic and quasielastic neutron scattering.
We studied the low-energy excitations in the meV region as well as the picosecond fast process in polystyrene thin supported films using inelastic and quasielastic neutron scattering in a temperature range from 11 to 430 K , covering the bulk glass transition temperature Tg. It was found that the mean square displacement u2 decreased with the film thickness below and above the glass transition ...
متن کاملStudy of low-energy magnetic excitations in single-crystalline CeIn3 by inelastic neutron scattering
Inelastic neutron scattering experiments were performed on single crystals of the heavy-fermion compound CeIn3 for temperatures below and above the Néel temperature, TN . In the antiferromagnetically ordered phase, well-defined spinwave excitations with a bandwidth of 2 meV are observed. The spin waves coexist with quasielastic (QE) Kondo-type spin-fluctuations and broadened crystal-field (CF) ...

متن کاملMagnetic excitations in the low-temperature ferroelectric phase of multiferroic YMn2O5 using inelastic neutron scattering.
We studied magnetic excitations in a low-temperature ferroelectric phase of the multiferroic YMn(2)O(5) using inelastic neutron scattering (INS). We identify low-energy magnon modes and establish a correspondence between the magnon peaks observed by INS and electromagnon peaks observed in optical absorption [A. B. Sushkov et al., Phys. Rev. Lett. 98, 027202 (2007).]. Furthermore, we explain the...
