Abstract
We report extended X-ray-absorption fine structure measurements on the A1 and Mn K absorption edges in icosahedral AlMnSi quasicrystals as well as in the α-AlMnSi phase. We find close resemblance between the α and i phases around an aluminium atom but poorer agreement around a manganese atom. The local order is discussed within the framework of the Mackay icosahedron model.Keywords
