Determination of the partial structure factors in (FexMn1-x)35Y65metallic glasses by neutron diffraction

Abstract
The Faber-Ziman and Bhatia-Thornton structure factors of (FexMn1-x)35Y65 metallic glasses have been determined by neutron diffraction using the isomorphous substitution method between Fe and Mn atoms. These glasses behave as segregating glasses with a CSRO parameter alpha 1 of 0.07. The type of atomic arrangement is completely opposite to that found previously for the Ni33Y67 glass. Using an electronic approach the authors show that strong changes in the electronic structure of both alloys can explain the difference.
