Ion Irradiation Studies of Soft Magnetic Metallic Glasses

Finemet and Vitrovac±R 6025 metallic glasses were irradiated by light (N) and heavy (Au and Ta) ions at different energies from 110 keV to 250 MeV/u (MeV per mass unit) and fluences from 1 £ 1011 ions/cm2 to 1£1017 ions/cm2. They were analysed by the Mossbauer spectrometry and magnetic susceptibility measurements. Qualitative differences were observed between the radiation effects caused by light and heavy ions.
