Description
We report extended x-ray-absorption fine-structure measurements on the Mn and Ru K absorption edges in rapidly quenched icosahedral alloys of Al/sub 86/Mn/sub 14/, Al/sub 75.5/Mn/sub 17.5/Ru4Si 3, and Al/sub 75.5/Mn/sub 15.5/Ru6Si 3, as well as the crystalline forms of Al6Mn and Al6Ru. In the icosahedral phase, we find an asymmetric distribution of Al atoms around Mn sites, containing at least two Al-Mn distances. The asymmetry becomes more pronounced with increasing Ru content. The Ru atomic environment appears to include an additional very short Ru: Al or Ru: Si bond
