中文摘要 | The point-contact Andreev reflection spectroscopy for a simple BCS type-II superconductor was investigated in pure niobium (Nb). The small broadening factor of Gamma/Delta(0)< 0.09 was achieved by careful preparation of the junctions. Then we attempted to use the recently proposed two-channel model [Phys. Rev. B 72, 012502 (2005)] to explain the spectra measured in various magnetic fields for such low-Gamma case. It was found that this rigid vortex core model is appropriate below a crossover field H-*, above which it is not adequate due to the onset of substantial vortex overlapping effect. |
