Description

We report on the recent progress in the development of the longitudinal MIEZE (Modulation of IntEnsity with Zero Effort) technique at the resonant neutron spin echo spectrometer RESEDA [1] at the Heinz Maier-Leibnitz Zentrum. The key technical parameters, such as the large dynamical range and possible sample environments are discussed. Typical experimental data comprising quasi-elastic and inelastic scattering are presented to highlight the versatility of the MIEZE technique. These data include magneto-elastic coupling and crystal field excitations in Ho₂Ti₂O₇, the skyrmion lattice to paramagnetic transition under applied magnetic fields in MnSi, ferromagnetic criticality and spin waves in Fe as well as molecular dynamics in H₂O.
