- 論文の詳細を見る
We report the results of NQR (nuclear quadrupole resonance) study on SmRu_4P_<12>, one of a few candidates for materials showing octupolar ordering. In this study, we firstly succeeded in observing the ^<101>Ru-NQR signal in filled skutterudite compounds RRu_4P_<12> (R: rare earth). A single ^<101>Ru-NQR signal splits into two resonance lines, having intensity ratio of 3:1, just below the metal-insulator (M-I) transition temperature of 16.5K. This result gives convincing evidence for symmetry lowering in the ordered state of this compound, namely the cubic Im3^^- space group for the filled skutterudite compounds is lowered to the trigonal R3^^-. The model of the ordered structure characterized by a wave vector q=(1,0,0) satisfactorily explains the observed phenomena in the present study and the M-I transition in this compound.
