Correlation of magnetic properties with the local features of the electronic and crystal structure in theCe$_2$Fe$_{17-x}$Mn$_x$ intermetallide: XAFS data analysis

The rearrangement of the local environment of cerium has been examined using extended X-ray absorption fine structure spectroscopy above the $K$-Ce absorption edge for various manganese contents and temperatures in Ce$_2$Fe$_{17-x}$Mn$_x$ intermetallics ($x = 0, 1, 2$). The valence state of cerium has been studied simultaneously by X-ray absorption near-edge structure spectroscopy above the $L_3$-Ce absorption under the same conditions. A correlation has been revealed between the changes observed in the local electronic and crystal structure of Ce$_2$Fe$_{17-x}$Mn$_x$ compounds and the types of magnetic states in them.
