Zusammenfassung:The rearrangement of cerium and lutetium local environment in Ce2Fe17−xMnx and Lu2Fe17-xMnx intermetallics vs. Mn concentration and temperature was investigated by means of the extended X-ray absorption fine structure (EXAFS) spectroscopy above K-Ce absorption edge and powder X-ray diffraction. The valence state of Ce in Ce2Fe17−xMnx was also studied by X-ray absorption near-edge structure (XANES) spectroscopy above L3-Ce absorption edge. The correlation between changes in local electronic and crystal structure and the types of magnetic ordering in these compounds is discussed.
