4 and the itinerant helimagnet MnSi. The domain of chiral magnetism currently attracts a great deal of scientific interest in various fields of condensed matter physics, e.g. magnetic surfaces and interfaces, spintronics, multiferroics.
Our investigation with polarised neutrons unambiguously determined the magnetic structure of NdFe

In addition inelastic neutron scattering experiments in MnSi identified the existence of a new type of magnetic Goldstone modes, namely the helimagnons, that were predicted by theorie recently.
