Effect of high-energy ion irradiation on the elastic moduli of Ag/Co superlattices

Abstract
The elastic moduli of Ag/Co superlattice structures have been studied by Brillouin scattering, as a function of irradiation with 6-MeV C+ ions. A hardening of the superlattice structures with increasing dose was observed. These results imply that the elastic-constant anomalies in metallic superlattices are due to the strains present. The origin of the strains, however, cannot be uniquely identified.
