Multi-symmetry and Multi-band Superconductivity in Filled-skutterudites PrOs${}_4$Sb${}_{12}$ and PrRu${}_4$Sb${}_{12}$

R. W. Hill, Shiyan Li, M. B. Maple +1

Thermal conductivity measurements were performed on single crystal samples of the superconducting filled skutterudite compounds PrOs${}_4$Sb${}_{12}$ and PrRu${}_4$Sb${}_{12}$ both as a fu…
