Neutron scattering from FeSi

The inelastic neutron scattering from the unusual paramagnet FeSi has been measured at temperatures of up to 700 K in order to investigate the possible existence of a local magnetic moment at high temperatures. The estimated intensities of the central peaks around $\text{h}\text{?}\text{ω = 0}$ and the nearly constant backgrounds ($\text{h}\text{?}\text{ω ? 16 meV}$) indicate that the paramagnetic state above 600 K in FeSi cannot be interpreted in terms of a simple localized spin model with $\text{S ～}\text{1}\text{2}$.
