Thermoelectric and optical properties of the filled skutterudite YbFe4Sb12

Transport measurements, including magnetoresistivity, Hall resistivity, thermal conductivity, and thermopower, and an assessment of the dimensionless thermoelectric figure of merit ZT below room temperature are reported on a polycrystalline sample of the strongly correlated electron material YbFe4Sb12 . Neutron diffraction measurements are presented, which reveal large amplitude thermal vibrati...

Charge-doping-driven evolution of magnetism and non-Fermi-liquid behavior in the filled skutterudite CePt4Ge(12-x)Sb(x).

The filled skutterudite compound CePt(4)Ge(12) is situated close to the border between the intermediate valence of Ce and heavy-fermion behavior. Substitution of Ge by Sb drives the system into a strongly correlated and, ultimately, upon further increasing the Sb concentration, an antiferromagnetically ordered state. Our experiments evidence a delicate interplay of emerging Kondo physics and th...

Heavy fermion superconductivity in the filled skutterudite compoundPrOs4Sb12

The filled skutterudite compound PrOs4Sb12 has been found to exhibit superconductivity with a critical temperature Tc = 1.85 K that develops out of a heavy Fermi liquid with an effective mass m ∗ ≈ 50 me. The current experimental situation regarding the heavy fermion state, the superconducting state, and a high field, low temperature phase that is apparently associated with magnetic or quadrupo...
