  We calculate the Andreev spectroscopy between a ferromagnetic lead and Bi/Ni
bilayer system for three types of superconducting states, including ABM state,
ABM state mixing with S-wave state, ABM state mixing with pz-wave state. Among
them, ABM state and ABM state mixing with S- wave state can obtain the Andreev
conductance consistent with the point contact experiment[G. J. Zhao,et al,
arXiv:1810.10403], but failed to explain the experiment of time-domain THz
spectroscopy experiment[Prashant Chauhan,et al, Phys. Rev. Lett. 122,
017002(2019)]. Only the ABM state mixing with pz-wave state can explain both
experiments. Besides, we reveal the conductance peak near the zero energy is
induced by the surface state of the ABM phase. Our work may provides helpful
clarification for understanding of recent experiments.
