摘要：

We have carried out the P-31-NMR measurements on the filled skutterudite compound SmFe4P12, and observed the ferromagnetic heavy fermion behavior. The P-31-NMR spectra show that the system remains in the paramagnetic state above the Curie temperature T-C. The temperature T and the applied magnetic field dependences of the spin-lattice relaxation rate 1/T-1 indicate the heavy fermion behavior (1/T-1 Tsimilar toconstant) in the range of T = 7.5-25 K and the ferromagnetic fluctuations of the Sm moments above the T-C.
