Abstract

The tunnel conductance in normal-metal/insulator/PrOs₄Sb ₁₂ junctions is theoretically studied, where skutterudite PrOs ₄Sb₁₂ is considered to be an unconventional superconductor. The conductance is calculated for several pair potentials which have been proposed in recent papers. The results show that the conductance spectra are sensitive to the relation between the direction of electric currents and the position of point nodes. Generally speaking, the tunnel spectra are believed to reflect the density of states in superconductor. The calculated results, however, often deviate from the shape of bulk density of states.
