Helimagnets studied with neutron spin echo at RESEDA — •Jonas Kindervater1,2, Wolfgang Häußler1,2, Alexander Tischendorf1,2, Andreas Bauer1, Christian Pfleiderer1, and Peter Böni11Technische Universität München, Physik Departement E21, 85748 Garching, Germany — 2Forschungs-Neutronenquelle Heinz Maier-Leibnitz (FRMII), 85748 Garching, Germany

Using RESEDA (FRM II, Munich), several studies on magnetic fluctuations in ferro- and helimagnetic compounds have been performed. RESEDA uses the Neutron Resonance Spin Echo (NRSE) technique, being a variant of conventional Neutron Spin Echo (NSE). In NRSE as in NSE, the beam polarization is the measured quantity. It provides the intermediate scattering function yielding information on the slow dynamics of the sample. However, NRSE experiments on magnetic systems, which affect the beam polarization, are difficult or even not feasible at all. In this contribution, we present the results of elastic and quasi-elastic scattering experiments on manganese silicide. We summarize the data analysis, proofing the polarizing effect of the sample, and taking into account this feature in the normalization of the results from quasi-elastic measurements.
