Tests of Modulated Intensity Small Angle Scattering in time of flight mode
G. Brandl, J. Lal, J. Carpenter +5
We report results of tests of the MISANS technique at the CG-1D beamline at High Flux Isotope Reactor (HFIR), Oak Ridge National Laboratory (ORNL). A chopper at 40 Hz simulated a p…
Large Scales - Long Times: Adding High Energy Resolution to SANS
G. Brandl, R. Georgii, W. Häußler +2
The Neutron Spin Echo (NSE) variant MIEZE (Modulation of IntEnsity by Zero Effort), where all beam manipulations are performed before the sample position, offers the possibility to…
Long-range crystalline nature of the skyrmion lattice in MnSi
T. Adams, S. Mühlbauer, C. Pfleiderer +9
We report small angle neutron scattering of the skyrmion lattice in MnSi using an experimental set-up that minimizes the effects of demagnetizing fields and double scattering. Unde…
Inelastic Neutron and X-ray Scattering from Incommensurate Magnetic Systems
Peter Böni, Bertrand Roessli, Klaudia Hradil
Neutrons and X-rays are powerful probes for studying magnetic and lattice excitations in strongly correlated materials over very wide ranges of momentum and energy transfers. In th…
Turn-key module for neutron scattering with sub-micro-eV resolution
Robert Georgii, Georg Brandl, Nikolas Arend +5
We report the development of a compact turn-key module that boosts the resolution in quasi-elastic neutron scattering by several orders of magnitude down to the low sub-micro-eV ra…
Time Resolved Stroboscopic Neutron Scattering of Vortex Lattice Dynamics in Superconducting Niobium
S. Mühlbauer, C. Pfleiderer, P. Böni +5
Superconducting vortex lattices, glasses and liquids attract great interest as model systems of crystallization and as a source of microscopic information of the nature of supercon…
