Thin films prepared by vacuum evaporation of
57
Fe and subsequent low energy ion implantation were investigated by conversion electron Mössbauer spectroscopy and AFM measurements. A sextet with Mössbauer parameters of
δ
= 0.1 mm/s and
B
= 26 T appearing in the CEM spectra was identified as amorphous iron. Passivation and phosphonation of the thin films revealed the high affinity of amorphous iron in chemical reactions.
