摘要：

Muon spin relaxation measurements on the filled skutterudite compound SmRu4P12 have been carried out in zero and longitudinal fields. The temperature dependence of both the initial asymmetry and the muon spin depolarization rate shows the appearance of a magnetically ordered state below the metal-insulator transition temperature T-MI. The present study indicates that the ordering below T-MI is not a nonmagnetic antiferroquadrupolar ordering but a magnetic one, which supports a scenario that magnetic octupolar ordering occurs below T-MI in SmRu4P12.
