Abstract
The effect of weakly bound magnetic impurity atoms (Mn, Er) on the spin-wave spectrum of Fe has been studied by incoherent inelastic neutron scattering. Resonances of magnetic origin have been observed in both cases. In Fe-Mn the angular distribution of the total scattered intensity has a maximum, indicating that SMn≠0 and the density distribution of magnetic electrons of iron atoms near the Mn impurity has changed. In Fe-Er, a low-lying virtual level of long lifetime was found.This publication has 5 references indexed in Scilit:
