摘要：

In this work we present a neutron powder diffraction study of the ternary rare-earth phosphides PrFe4P12 and NdFe4P12. High-resolution measurements of the structural temperature dependence reveal large-amplitude thermal vibrations of the rare-earth ions, consistent with speculations that the ion is weakly bound in an oversized atomic 'cage' formed in the skutterudite crystal structure. In addition, low temperature neutron diffraction measurements of RFe4P12 (R=Pr, Nd) were performed. Whereas the proposed long-range antiferromagnetic ordering in PrFe4P12 could not be confirmed, NdFe4P12 orders ferromagnetically below T-C = 1.94 K with an ordered magnetic Nd3+ moment of 1.61(7) mu (B) at 1.5 K.
