Research Abstract

We have performed systematic ultrasonic measurement on 3-20-6 type clathrate compounds and filled-skutterudite compounds to elucidate rattling and tunneling with cage-like nano-space. In the R_3Pd_20Ge_6 multi-structured ultrasonic dispersions in the elastic constant C_44 were observed. On the other hand, we revealed rattling does not emerge in the R_3Pd_20Si_6. These results evidences that conduction bands participate in the formation of anharmonic vibration with Γ_5-type charge fluctuation using the path of electron-phonon interaction. In addition, we found antiferro-type qoadrupole ordering of 8c site at 250 mK and successively of 4a site at 60 mK in Pr_3Pd_20Ge_6.
