M. Sakurai et al., NANOMETRIC STRUCTURE OF FE CLUSTERS IN FE CU AND FE/AG GRANULAR-MATERIALS STUDIED BY EXAFS/, Physica. B, Condensed matter, 209(1-4), 1995, pp. 614-616
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%.
