Dynamics of cubic-tetragonal phase transition in KNbO$_3$ perovskite

, 2004
The low-energy part of the vibration spectrum in KNbO$_3$ was studied by cold neutron inelastic scattering in the cubic phase. In addition to acoustic phonons, we observe strong diffuse scattering, which consists of two components. The first one is quasi-

Direct measurement of individual phonon lifetimes in the clathrate compound Ba7.81Ge40.67Au5.33

Nature Communications, 2017
Phonon lifetime is a fundamental parameter of thermal transport however its determination is challenging. Using inelastic neutron scattering and the neutron resonant spin-echo technique, Lory et al.

Inelastic Scattering of Cold Neutrons [PDF]

Nature, 1951
THE gain of energy of cold neutrons on being scattered by crystalline materials has been investigated with a beam of lead-filtered neutrons from the Harwell pile. The maximum energy of the neutrons in the beam was 0.0026 eV. and the mean energy was 0.0017 eV. The experimental arrangement is shown in the accompanying diagram. The counter and sample were

Neutron spin structure from polarized deuteron DIS with proton tagging

Physics Letters B, 2019
Polarized electron-deuteron deep-inelastic scattering (DIS) with detection of the spectator proton (“tagged DIS”) enables measurements of neutron spin structure with maximal control of nuclear effects.

Emergence of a Hidden Magnetic Phase in LaFe11.8Si1.2 Investigated by Inelastic Neutron Scattering as a Function of Magnetic Field and Temperature

Advanced Physics Research
The NaZn13 type itinerant magnet LaFe13−xSix has seen considerable interest due to its unique combination of large magnetocaloric effect and low hysteresis.

Instrumental aspects

EPJ Web of Conferences, 2017
Every neutron scattering experiment requires the choice of a suited neutron diffractometer (or spectrometer in the case of inelastic scattering) with its optimal configuration in order to accomplish the experimental tasks in the most successful way. Most
