This contribution presents experimental data concerning the influence of fast heavy ions on magnetic susceptibility of VITROVAC®6025 and VITROPERM®800 metallic glasses. Samples of magnetic ribbons were irradiated with Au, and Ta ions at 11.1 MeV/A (energy per nucleon), and U ions at 5.9 MeV/A. The irradiation fluences varied from 5×10^{10} up to 1.2×10^{13} ions/cm^{2}. Relative change of the samples' magnetic susceptibility after and before irradiation was measured and evaluated as a function of the irradiation fluence. Measurements were done with a commercial Kappa-bridge device. We observed that VITROPERM® showed less change of magnetic susceptibility in comparison with VITROVAC® and this change occurred at higher fluences. This indicates higher radiation hardness of VITROPERM® compared with VITROVAC® against high-energy heavy ions. In addition, heavier ions caused larger change of magnetic susceptibility than the lighter ones and the effect could be roughly scaled with the level of electronic stopping.
