Tunneling and rattling in clathrate crystal
Terutaka Goto, Yuichi Nemoto, Takashi Yamaguchi +4
We present tunneling and rattling motions of an off-center guest atom in cage referring to a clathrate crystal La_3Pd_{20}Ge_6. The elastic constant C_{44} of La_3Pd_{20}Ge_6 shows…

Quadrupolar effect and rattling motion in heavy fermion superconductor PrOs_4Sb_{12}
Terutaka Goto, Yuichi Nemoto, Kazuhiro Sakai +7
The elastic properties of a filled skutterudite PrOs_4Sb_{12} with a heavy Fermion superconductivity at T_C=1.85 K have been investigated. The elastic softening of (C_{11}-C_{12})/…

Ferroquadrupole ordering and Gamma_5 rattling motion in clathrate compound Ce_3Pd_20Ge_6
Yuichi Nemoto, Takashi Yamaguchi, Takenobu Horino +6
Lattice effects in a cerium based clathrate compound Ce_3Pd_20Ge_6 with a cubic Cr_23C_6-type structure have been investigated by ultrasonic and thermal expansion measurements. Ela…
