Abstract
The local structure around Fe in Fe/Cu and Fe/Ag granular materials ha s been studied by means of extended X-ray absorption fine structure (E XAFS). In the Cu matrix, the structure of the Fe cluster is FCC for Fe concentrations less than 22 at%, while it is BCC for more than 35 at% Fe. In the Ag matrix, on the other hand, the structure of the Fe clus ter is BCC even for Fe concentrations down to 12 at%.
