概要

• 論文の詳細を見る

• We have made ultrasonic measurements on a filled skutterudite PrOs_4Sb_<12> showing a heavy fermion superconductivity at T_C=1.85 K. The softening of the elastic constant with decreasing temperature has been found above T_C. The (C_<11>-C_<12>)/2 in applying magnetic fields along the [110] axis at 1.0 K exhibits a minimum around 8T, which is well accounted for by the one-ion quadrupolar susceptibility reflecting the level crossing of one of an excited Г^<(2)>_4 triplet to a ground state Г_1 singlet. The softening of (C_<11>-C_<12>)/2 proportional to reciprocal temperature just above T_C may be dominated by the tunneling of an off-center Pr-ion in an Sb-icosahedron cage.
