Abstract: Iron nanocrystalline powder was prepared by the reduction of ferrihydride. The samples were sealed in Ar in a plastic bag to avoid any contact with air in the form of (i) the as-prepared powder, (ii) the powder mixed with a vacuum grease, and (iii) the powder after a very slow oxidation at room temperature which formed an oxidic shell. Their phase compositions were investigated by XRD and Mossbauer spectroscopy. These data were completed by magnetic measurements. The intense amorphous-like component was observed in the Mossbauer spectrum of the as-prepared powder. The origin of this component is discussed.
