We propose a model of nodal order parameters for the superconducting A- and B-phase of skutterudite PrOs<sub>4</sub>Sb<sub>12</sub> and discuss the associated angular-dependent magnetothermal conductivity at low temperatures. The model for the hybrid gap functions Δ(k) containing s- and g-wave parts is consistent with recent thermal-conductivity experiments in PrOs<sub>4</sub>Sb<sub>12</sub>. In particular, the model accounts for the data on the polar and azimuthal field angle dependence of κ<sub>zz</sub>(θ,φ). The low-temperature behaviour of thermodynamic properties in zero field is also presented. We show that the effect of impurity scattering on a nodal hybrid gap function immediately leads the opening of a gap and the related exponential behaviour of low-temperature specific heat and thermal conductivity which is very different from d-wave superconductors. |
