Short range order around Sc atoms in Fe90Sc10 nanoglasses using fluorescence X-ray absorption spectroscopy

Abstract

X-ray absorption spectroscopy has been applied to probe the local structure of FeSc nanostructured amorphous solids around Sc atoms. At the Sc K-edge, the Fe90Sc10 nanoglass is characterized by a very short range order (EXAFS oscillations are only present up to k = 8 Å-1). A drastic difference in the phase and the amplitude of the nanoglass EXAFS signal compared to the amorphous ribbon indicating a different local structure around Sc atoms in both structures is observed. In addition, the changes in the local structure around Sc atoms are more significant than around Fe atoms.
