Аннотация
Elastic (G) and inelastic (Q–1) properties of the Cox(CaF2)100 –x (x = 41–84 at %) nanocomposites fabricated with the aid of ion-beam sputtering are studied in a temperature interval of 170–750 K. Maximum internal friction related to hopping of Co atoms inside metal granules is revealed at a temperature of 227 K. It is shown that the maxima increase with increasing concentration of metal phase. A noticeable increase in dependence Q–1(T) at a temperature of greater than 675 K is caused by diffusion of vacancies in the Co granules under geometrical confinements.
