Abstract

We study tunneling conductance in normal metal-insulator-ferromagnetic superconductor junctions. The tunneling spectra show a clear difference between spin-singlet s-wave pairing, spin-triplet opposite spin pairing, and spin-triplet equal spin pairing: These pairings exhibit, respectively, gap structure, double peak structure, and zero-bias peak in the spectra. The obtained result may serve as a tool for determining the pairing symmetry of ferromagnetic superconductors.
