Novel Phase Transition Near the Quantum Critical Point in the Filled-Skutterudite Compound CeOs4Sb12: an Sb-NQR Study
Mamoru Yogi, Hisashi Kotegawa, Guo-qing Zheng +4
We report on a novel phase transition at = 0.9 K in the Ce-based filled-skutterudite compound CeOsSb via measurements of the nuclear-spin lattice relaxation rate $…
Specific Heat Study on Heavy-Fermion Pr compounds with filled skutterudite structure
Y. Aoki, T. Namiki, T. Kanayama +4
Rare 4f^2-based heavy-fermion behaviors have been revealed recently in Pr-based filled skutterudites PrFe4P12 and PrOs4Sb12. Recent studies on the thermal properties on both compou…
Evidence for Unconventional Strong-coupling Superconductivity in PrOs_4Sb_12 : An Sb Nuclear Quadrupole Resonance (NQR) Study
H. Kotegawa, M. Yogi, Y. Imamura +7
We report Sb-NQR results which evidence a heavy-fermion (HF) behavior and an unconventional superconducting (SC) property in the filled-skutterudite compound PrOs_4Sb_12 revealing…
Thermodynamical Study on the Heavy-Fermion Superconductor PrOs4Sb12: Evidence for Field-Induced Phase Transition
Y. Aoki, T. Namiki, S. Ohsaki +3
We report measurements of low-temperature specific heat on the 4f^2-based heavy-fermion superconductor PrOs4Sb12. In magnetic fields above 4.5 T in the normal state, distinct anoma…
