| 中文摘要 | Electron-tunneling spectroscopy on MgCNi3 has been studied with N/MgCNi3 point contacts with N=PtIr and Au. Most of the measured tunneling conductance show an Andreev reflection peak and a pronounced dip structure outside the peak. We introduce a Josephson junction in series with the point contact to model the tunneling process. By tuning the weights of the point contact quasiparticle voltage and the Josephson voltage we are able to fit almost all the tunneling data nicely. The results support BCS s-wave pairing in MgCNi3, and the model explains the sharp dip structure which is seen in point contact tunneling into some polycrystalline superconductors. |
