31P-NMR and studies of filled skutterudite compounds RRu4P12 (R: Sm, Gd)

Novel electronic states realized in the filled skutterudites containing rare earth elements with more than one 4f-electrons

“…However, the breaking of time reversal symmetry has been proposed based on the ultrasonic measurements below T MI caused an octupole ordering [46]. The scenario has been further reinforced by mSR experiments [47] and the 149 Sm nuclear forward scattering experiment [48]. SmOs 4 Sb 12 was reported to be a HF material with the heaviest mass of g4800 mJ/mol-K 2 among Sm-based materials by Sanada et al [49] and Yuhasz et al [50].…”
