摘要：

This work is an extensive study of the cubic Laves phase rare earth compounds: CeFe2 and its related hydrides performed by X-ray absorption spectroscopy. The CeFe2 system has been investigated by Extended X-ray Absorption Fine Structure (EXAFS) both at cerium and iron sites and by X-ray Absorption Near Edge Spectroscopy (XANES) at different edges of both cerium and iron atomic species. Attempts to relate magnetic properties of this system with the electronic properties and the crystal structure of the disordered hydridate phases have been performed.
