Title:
Helimagnon Bands as Universal Excitations of Chiral Magnets 
Abstract:
MnSi is a cubic compound with small magnetic anisotropy, which stabilizes a helimagnetic spin spiral that reduces to a ferromagnetic and antiferromagnetic state in the long- and short-wavelength limits, respectively. We report a comprehensive inelastic neutron-scattering study of the collective magnetic excitations in the helimagnetic state of MnSi. In our study we observe a rich variety of seemingly anomalous excitation spectra, as measured in well over 20 different locations in reciprocal spac...    »
