摘要：
Using extended X-ray absorption fine-structure experiments performed above the Ru, Cu and Fe K absorption edges, the local order around respectively Cu and Ru, Cu and Fe has been determined in icosahedral Al65Cu20Ru15 and in rhombohedral Al62.8Cu26Fe11.2. Strong resemblances are observed in the environments of Cu and of Ru or Fe atoms in these alloys and in icosahedral Al63Cu24.5Fe12.5. Chemical ordering between Al and Ru or between Al and Fe atoms has been found. Correlations with the electronic structure are made.
