EXAFS SPECTROSCOPY OF AMORPHOUS Fe-Ni STEELS

We have investigated the local disorder of Fe80B20 and Fe40Ni40B6P14 glasses. The asymmetric peak of F (r) obtained from EXAFS (Extended X-Ray Absorption Fine Structure) studies is believed to be due to a sizeable backscattering contribution of the metal-metal pairs. The metal-metalloid arrangement cannot be definitely assigned using the EXAFS data alone. Near-edge K-absorption spectra support a strong hybridization involving the d-p bands of metal and B (or P)
