In this study,we investigate the tunneling conductance at a finite temperature in a normalmetal/ferromagnetic superconductor nano-junction where the ferromagnetic superconductor(FS)is in three differentcooper pairing states: spin singlet s-wave pairing(SWP),spin triplet opposite spin pairing(OSP),and spin triplet equalspin pairing(ESP)while including Fermi wave mismatch(FWM)and effective mass mismatch(EMM)in two sides ofthe nano-junction.We find that the conductance shows clearly different behaviors all depending on the symmetries ofcooper pairing in a manner that the conductance spectra shows a gap-like structure,two interior dips structure and zerobias peak for SWP,OSP,and ESP,respectively.Also,the effective FS gap(△_(eff))is a linear and decreasing function ofexchange field.The slope of(△_(eff))versus exchange field for OSP is twice the SWP.Thus,we can determine the spinpolarization of N/FS nano-junction based on the dependence of(△_(eff))to exchange Held.

We find that the conductance shows clearly different behaviors all depending on the symmetries ofcooper pairing in a manner that the conductance spectra spectra of a gap-like structure, two interior dips structure and zerobias peak for SWP, OSP, and ESP, respectively. Als, the effective FS gap (Δ_ (eff)) is a linear and (△ _ (eff)) versus exchange field for OSP is twice the SWP.Thus, we can determine the spinpolarization of N / FS nano-junction based on the dependence of (△ _ (eff) ) to exchange Held.
