Abstract
Fe-57 Mossbauer spectroscopy is used to study neutron irradiation indu ced changes in the short-range order of Fe73.5Nb3Cu1Si13.5B9 alloy. Th e samples are investigated in both amorphous and nanocrystalline state s. Neutron irradiation leads to an increase of the standard deviation of a hyperfine field distribution (HFD), implying rearrangement of the atoms towards disordering. Simultaneously, changes in the average val ue of the hyperfine field and a net magnetic moment position occur as a consequence of a spin reorientation, atom mixing and microscopic str ess centres which are introduced by neutron irradiation.
