Abstract We study zero-bias conductance (ZBC) spectra of a normal-metal/insulator/singlet (and triplet) ferromagnetic superconductor as a function of potential strength of interface in the Blonder–Tinkham–Klapwijk (BTK) theory framework. We consider possible pairing states including spin singlet s-wave pairing (SWP), spin triplet opposite spin pairing (OSP) and spin triplet equal spin pairing (ESP). It is found that ZBC as a function of potential strength of interface shows a clear difference between SWP, OSP and ESP states. These results may serve as a useful tool for discriminating pairing states in ferromagnetic superconductors.
