Tunneling conductance in graphene ferromagnet/ superconductor junctions at finite temperature

Using the extended Blonder-Tinkham-Klapwijk formalism, we investigate the conductance spectra of graphene ferromagnet /p wave superconductor junctions at finite temperature. It is found that the conductance spectra at finite temperature are affected by the p wave pairing symmetry. The ferromagnetic exchange energy in the ferromagnet can suppress Andreev retroreflection but enhance the specular Andreev reflection in graphene ferromagnet / p wave superconductor junctions at finite temperature.
