Abstract: Based on the extended Blonder-Tinkham-Klapwijk formalism, the tunnelingconductance characteristics of a planar junction between a ferromagnet and anoncentrosymmetric superconductor are studied. The effects of the Rashbaspin-orbit coupling RSOC, the exchange energy, and the Fermi wave-vectormismatch FWM on the conductance are all taken into account. In the absence ofthe FWM, it is found that far away from the gap edge the conductance issuppressed by the RSOC, while around the gap edge it is almost independent ofRSOC. The interplay of the RSOC and the exchange energy causes an enhancementof the subgap conductance, which is more pronounced when the RSOC is small.When the FWM is introduced, it is shown that the conductance is monotonicallyenhanced as the FWM parameter decreases.
