Magnon Dispersion in CeIn3
This dataset contains measurements of the low-energetic magnetic excitations in the heavy-fermion material CeIn3. Neutron spectroscopy data were recorded on a single-crystal mosaic of around 2 g total mass at the spectrometer CNCS. In a first row of measurements with incident neutron energy 12 meV the excitations were mapped out in major parts of the first Brillouin zone. In a second row of measurements with 3.315 meV incident neutron energy, the gapless and relatively steep dispersion in the vicinity of the R-point, corresponding to (1/2,1/2,1/2) in reciprocal space, was investigated.
