An experimental method of collecting high-resolution neutron powder diffraction data in a wide angular range on permanently rotating prismatic Li-ion batteries cell, which allows to eliminate a need of complex absorption correction due to highly anisotropic attenuation paths for thermal neutrons in prismatic cells, is proposed. Neutron diffraction data, in quality enabling Rietveld refinement, was collected ex situ at discrete (predefined) cell states-of-charge (SOC = 100% and 0%). [...]

While the influence of dipolar interactions on the spin-wave dispersion in ferromagnets with localized magnetic moments has been studied in detail, similar studies in itinerant electron systems are rather scarce due to experimental difficulties. Using the newly developed neutron Larmor precession technique MIEZE in a longitudinal field configuration, we succeeded to map out the spin-wave dispersion in Fe at small momentum q and energy transfers E.
