Radiation Damage Induced by Electronic-Energy Loss in Amorphous Metallic Alloys

Abstract

The electrical resistance of amorphous metallic Fe85B15 ribbons irradiated with 3 GeV Xe ions at different tilting angles with respect to the incident ion beam has been measured in situ at 77 K. The results show that irradiation induces large sample growth due to electronic-energy loss effects. The existence of a new mechanism leading to damage creation in metallic alloys by electronic excitation alone is also demonstrated.
