Incommensurate magnetic systems studied with the multi-purpose three-axis spectrometer (TAS) MIRA at FRM II — •Robert Georgii¹, Tobias Weber^{1, 2}, Georg Brandl¹, and Peter Böni³ — ¹Maier-Leibnitz Zentrum (MLZ), Garching, Germany — ²Institut Laue Langevin (ILL), Grenoble, France — ³Physik Department E21, TU München, Garching, Germany

Incommensurate magnetic structures like Helimagnons and Skyrmions are currently intensively studied. Due to their large size and rigid structure they often show very low-lying excitations, where most of the interesting physics is taking place below some meV. The cold-neutron three-axis spectrometer MIRA is an instrument optimized for such low-energy excitations. Its excellent intrinsic resolution makes it ideal for studying incommensurate magnetic systems. Here we will present several examples for the dynamics of such structures which have been measured with MIRA.
