Abstract
We report the results of the intermediate valence compound EuCu 2Si 2 local electron and crystalline structure studies by means of L 3-Eu XANES and K-Cu EXAFS spectroscopy. Temperature dependence of the europium valence has been defined. In EXAFS studies, we have analyzed Cu atoms local environment and have revealed bond length and rigidity parameters of Cu–Si, Cu–Cu and Cu–Eu coordination spheres.
