Abstract :
We report the results of the intermediate valence compound EuCu2Si2 local electron and crystalline structure studies by means of L3-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.
