摘要
We have investigated the partially filled Skutterudite Pr0.5Pt4Ge12 for its superconducting properties. Resistivity measurements of Pr0.5Pt4Ge12 down to 2K and in the presence of fields up to 2T are reported. The superconducting transition, T-c of similar to 7.66K observed from zero fields of Resistivity and Heat Capacity measurements. The interesting observation is that the superconductivity survives even at a 50% filling of Pr in the parent compound and its Tc is equal to that of fully doped PrPt4Ge12. We have estimated relevant parameters of interest like the electron phonon coupling constant, critical field, energy gap ratio, coherence length etc.
