Abstract

The compositional dependence of the 57Fe Mossbauer effect spectra for the metallic glasses Y66(FexMn1-x)34 has been studied. For high concentrations of Fe the spectra consist of two symmetric peaks with the spectra becoming progressively more complex as the Fe content decreases. The smooth variation of the parameters derived from the spectra indicates that Fe and Mn perform the same functions in the glass. The author finds evidence for chemical ordering in these glasses and demonstrates the existence of two distinct atomic sites for Fe. Site 1 is attributed to Fe atoms having predominantly Y near neighbours and site 2 is identified as Fe atoms having a larger number of Fe (Mn) near neighbours.
