Abstract

The surface of amorphous metallic ribbons (Fe81B13.5Si3.5C2) irradiated with swift heavy ions is studied by atomic force microscopy (AFM). Ion impacts are materialized by the formation of hillocks for irradiations at 300 K with a high (dE/dx)e (above ∼55 keV nm-1). The height of the hillocks strongly decreases when the samples are aged during 1 year at room temperature. Conversely, irradiation at 80 K does not induce noticeable modifications of the surface of the ribbons. The results indicate that the formation of the hillocks, which are flattened by the sample growth, is essentially due to the damage created by electronic excitation in individual ion tracks.
