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.
