摘要
We present the magnetic properties of a filled skutterudite compound SmFe4P12. The magnetic-susceptibility and specific-heat measurements reveal a ferromagnetic phase transition at 1.6 K. The temperature dependence of the electrical resistivity exhibits a Kondo effect and the electronic specific heat coefficient attains as large as 370 mJ/mol K-2. This compound is thereby reported as the first Sm-based heavy fermion system with a ferromagnetic ground state. (C) 2003 Elsevier Science B.V. All rights reserved.
