The feasibility of endohedral iron doping of is studied using a mass selected ion beam to create an beam with variable energy (60–380 eV, C) which is directed at a thin film. The surface is characterized by x-ray photoelectron spectroscopy, and oxidation of the samples is used to discriminate between and carbides. The fullerene cages are damaged during the irradiation, and participate in direct Fe–C bond formation. The reaction with oxygen indicates the absence of sizable amount of Comparison with reference samples composed of iron and damaged fullerene layers (by irradiation) supports this interpretation. The experiment serves as a model study for the investigation of different metal-fullerene combinations.
