Abstract
Neutron-inelastic-scattering techniques have been used to study the spin dynamics of EuO. High-quality single crystals were used so that temperature-dependent line shapes could be obtained at all momentum values. It was found that the magnetic excitations above Tc changed from Lorentzian-like peaks centered at zero energy near the zone center to rather well-defined spin-wave-like excitations at the zone boundary.Keywords
