Abstract

An investigation of the bonding behaviours of selected rare earth (R) containing filled skutterudite samples (RFe₄P₁₂) is reported. X-ray diffraction and magnetic properties of CeFe₄P₁₂ are compared with those previously published. The electronic structure and bonding properties of the R La, Ce and Pr members of this series are probed by X-ray absorption near-edge spectroscopy (XANES), and compared with the L₃ edges of selected trivalent and tetravalent standards. We find that the Ce XANES is complex, indicating that although the Ce is primarily trivalent, there is evidence of complex electronic behaviour in CeFe₄P₁₂. A comparison of the L₃ edges of LaFe₄P₁₂, and PrFe₄P₁₂, as well as CeFe₄P₁₂, with those obtained from ionic model compounds reveals some bonding between the f-ion and the FeP framework in all cases.
