Intermetallic compounds containing f-electron elements display a wealth of superconducting
phases, which are prime candidates for unconventional pairing with complex order …

The heavy-fermion metal CeCu 2 Si 2 was the first discovered unconventional, non-phonon-
mediated superconductor and, for a long time, was believed to exhibit single-band d-wave …

Specific heat and transport measurements have revealed an unconventional heavy-fermion
(HF) state in SmOs 4 Sb 12 single crystals. The electronic specific-heat coefficient (γ= 0.82 …

Novel Kondo-like behaviors realized in the Pr-based filled skutterudites are reviewed based
on the electronic transport properties, specific heat and de Haas–van Alphen (dHvA) …

The results of inelastic neutron scattering provide a solution for the crystal field level scheme
in Pr⁡ O s 4 S b 12, in which the ground state in the cubic crystal field potential of T h …

A new calorimeter for measurements of the heat capacity and magnetocaloric effect of small
samples in pulsed magnetic fields is discussed for the exploration of thermal and …

This review presents a summary and evaluation of the experimental properties of
unconventional superconductivity in PrOs 4 Sb 12. After a brief introduction of filled …

Filled skutterudite compounds with a chemical formula AT4X12 (A= rare earth, actinide,
alkaline, or alkaline earth elements; T= Co, Ni, Rh, etc.; X= pnictogen) have been intensively …

We present new measurements of the specific heat of the heavy fermion superconductor
PrOs 4 Sb 12, on a sample which exhibits two sharp distinct anomalies at T c 1= 1.89 K and …

Low-lying singlet–triplet crystal-field levels are realized in Pr-based filled-skutterudite
compounds. The properties of multipolar moments in such systems are studied theoretically …
