Abstract
Triple-axis neutron spectroscopy has been used to study high-energy magnetic excitations for iron. The scattering contours established for the [100] and [111] directions show effects not present in localized-electron models of ferromagnetism. Interactions between spin waves and single-particle excitations are clearly seen for both crystallographic directions while two parts to the spin-wave branch are observed for the [100] direction.Keywords
