Abstract:
Neutron Spin Echo spectroscopy (NSE) uses polarized neutrons and in turn polarization analysis is an intrinsic feature of NSE. However, the multifaceted dynamics of antiferromagnets and helimagnets ask for more than the classical Neutron Spin Echo set-up (NSE). Here we present the feasibility test and first results of a new and powerful technique: Polarimetric NSE, obtained by combining the Wide Angle NSE spectrometer SPAN developed at HMI, with Cryopad, the spherical polarimetry equipment developed at ILL.
