Abstract:
The problems encountered in the analysis of EXAFS data from Fe40Ni40P14B6 are solved by assuming a micro-heterogeneous structure from chemically and structurally different micro-phases. A special Bayesian-type least-squares algorithm with general constraints was developed to reduce the effective number of free parameters, which fits simultaneously the EXAFS spectra at the NiK and the FeK edges and maximum prior knowledge as available. As a result of the analysis, the decomposition into micro-phase regions with Fe3B-type short-range order (52%) as well as random dense packed FeNiPB solid solution regions (48%) is proposed.
