摘要：

We present a combined x-ray-absorption-spectroscopy (XAS) and x-ray-circular-magnetic-dichroism (XCMD) study performed on the CeFe11TiHx systems. Looking at the changes of the local structure around the metal atoms by EXAFS (extended x-ray-absorption fine structure), the crystallographic position occupied by hydrogen in these compounds has been inferred. Moreover, the influence of hydrogen into the intermediate-valence state of Ce and the electronic localization is discussed. Both XAS and XCMD results evidence the strong correlation between the structural and magnetic changes associated to the modification of the hybridization between the Fe (3d) and Ce (5d) bands. © 1995 The American Physical Society.
