摘要：
The Sm-based filled skutterudite phosphides SmT4P12 (T = Fe, Ru, Os) have been studied by P-31-NMR (nuclear magnetic resonance) and mu SR (muon spin relaxation). The ferromagnetic order and the heavy fermion behavior in SmFe4P12 and the anti ferromagnetic order in SmOs4P12 were confirmed by P-31-NMR and mu SR. In SmRu4P12, a successive anomaly around the metal-insulator transition temperature and around the Neel temperature was observed by 31P-NMR in high applied magnetic fields. The mu SR results of SmRu4P12 indicate the magnetic order below the metal-insulator transition temperature, which supports the existence of the octupolar order in SmRu4P12.
