Static Correlation and Dynamical Properties of Tb3+-moments in Tb2Ti2O7 -Neutron Scattering Study- [PDF]

, 2002
Static and dynamical properties of the magnetic moment system of pyrochlore compound Tb2Ti2O7 with strong magnetic frustration, have been investigated down to the temperature T=0.4 K by neutron scattering on a single crystal sample. The scattering vector

Experimental neutron scattering evidence for proton polaron in hydrated metal oxide proton conductors

Nature Communications, 2017
Hydration of oxygen vacancies could form hydroxyl groups with interstitial structural protons. Here a quasi-elastic neutron scattering study reveals proton polarons in proton-conducting ceramic electrolytes, and the proton transport turns out to be a ...

Incoherent Neutron Scattering and Terahertz Time-Domain Spectroscopy on Protein and Hydration Water

Life, 2023
Incoherent inelastic and quasi-elastic neutron scattering (INS) and terahertz time-domain spectroscopy (THz-TDS) are spectroscopy methods that directly detect molecular dynamics, with an overlap in the measured energy regions of each method.

Notes on Fitting and Analysis Frameworks for QENS Spectra of (Soft) Colloid Suspensions [PDF]

EPJ Web of Conferences, 2022
With continuously improving signal-to-noise ratios, a statistically sound analysis of quasi-elastic neutron scattering (QENS) spectra requires to fit increasingly complex models which poses several challenges.

Polar rotor scattering as atomic-level origin of low mobility and thermal conductivity of perovskite CH3NH3PbI3

Nature Communications, 2017
Clarifying the atomistic behaviour of materials will lead to a deeper fundamental understanding and the rational design of future materials. Using time-of-flight quasi-elastic and inelastic neutron scattering measurements Liet al.

Quasi-free limit in the deuteron-deuteron three-body break-up process

SciPost Physics Proceedings, 2020
Detailed measurements of vector and tensor analyzing powers of the 2H(d, dp)n breakup process are presented. The data were obtained using a polarized deuteron-beam with an energy of 65 MeV/nucleon impinging on a liquid-deuterium target.

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-

Solvent contribution to the stability of a physical gel characterized by quasi-elastic neutron scattering [PDF]

, 2015
The dynamics of a physical gel, namely the Low Molecular Mass Organic Gelator {\textit Methyl-4,6-O-benzylidene-$\alpha$ -D-mannopyranoside ($\alpha$-manno)} in water and toluene are probed by neutron scattering.
