Free Electron-Like Stoner Excitation in Fe

Abstract
Methods have recently developed to probe the Stoner excitation spectrum which has not been amenable to study by neutron diffraction. The experiments have utilized energy loss spectroscopy combined with spin polarization of the incident electron beam or with spin polarization detection of the scattered beam, or both beam spin polarization and polarization detection [J. Kirschner, D. Rebenstorff, and M. Iback, Physical Review Letters 53, 698 (1984) (denoted by I)]. Due to the many possible scattering processes the experiments do not measure the Stoner excitation cross section directly but rather measure the magnitudes of combination of scattering amplitudes. To draw even semiquantitative conclusions regarding the Stoner spectrum requires theoretical analysis. Because Glazer and Tosatti [Solid State Communications 52, 905 (1984)] give more complete information than previous experiments it is possible for the first time to carry out a detailed theoretical analysis. The analysis concludes that free electronlike Stoner excitations (FESE) make a much larger contribution to the scattering than d electron Stoner excitations (DESE), the usual type.Citation
