Impurity Effect as a Probe for the Gap Function in the Filled Skutterudite Compound Superconductor PrOs${}_4$Sb${}_{12}$: Sb-NQR Study

Masahide Nishiyama, Takayuki Kato, Hitoshi Sugawara +4

We have carried out nuclear quadrupole resonance (NQR) measurements in the filled skutterudite compounds Pr(Os${}_{1-x}$Ru${}_x$)${}_4$Sb${}_{12}$ ($x=0.1,0.2$), in order to gain insights…
