Fluence and ion dependence of amorphous iron-phase-formation due to swift heavy ion irradiation in electrodeposited iron thin films

57Fe conversion electron Mössbauer spectroscopy, XRD and AFM measurements were used to study the radiation effect of 246 MeV Kr, 470 MeV Xe and 710 MeV Bi ions on electrochemically deposited iron thin films. It was found that, in the irradiated electrochemically deposited crystalline ferromagnetic α-Fe coatings, partial amorphisation of Fe took place. The relative amount of the ferromagnetic amorphous phase increased with both ion energy and ion mass as well as with the fluence of irradiation.
