"Spin fluctuations in the skutterudite compound LaFe₄Sb₁₂";
European Physical Journal B, 46 (2005), S. 257 - 267.

We report transport, magnetic and thermodynamic properties of the skutterudite compound LaFe4Sb12. The basic features are a large magnetic susceptibility , and large electronic coefficient of the heat capacity. In particular, a T1.35, T1.7, and T-2/3 temperature dependence of the magnetic susceptibility , resistivity , and Grüneisen parameter , respectively, is found at low temperature. An overall understanding of these physical properties is achieved, assuming that LaFe4Sb12 is a non-Fermi liquid system close to a ferromagnetic quantum critical point, with a spin fluctuation temperature K.
