abstract = "The Os substitution effects on the exotic metal-insulator (M-I) transition in the filled skutterudite compound SmRu4 P12 are studied by electrical resistivity and magnetic susceptibility measurements. Sm (Ru1 - x Osx)4 P12(x = 0.05, 0.10, 0.25, 0.50, 0.75) has been prepared at high temperature and high pressure. Twenty-five percent Os substitution almost suppresses the M-I transition. A resistivity minimum is observed around 50 K (Tmin) for all alloys and the minimum shifts with x. Furthermore, - log T dependence of resistivity below Tmin is also observed above x = 0.25. These facts suggest that the Sm-based filled skutterudite phosphides are Kondo systems.",
