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})/…
