Abstract

We present in this work an x-ray absorption spectroscopy (XAS) investigation performed at the L₃-edge of Ce in the intermetallic compounds Ce(Fe_1-xCo_x)₂ and Ce(Fe_1-xAl_x)₂. The mixed-valence behavior of Ce is found to be preserved in both series upon Fe substitution. This result rules out the development of a localized 4f magnetic moment at Ce atoms driven by the Fe-Co and Fe-Al substitution at the origin of the anomalous magnetic behavior of this series.
