| 中文摘要 | Physical properties have been comprehensively investigated on the noncentrosymmetric superconductor Ru7B3 with T-C=3.3 K. It is found that the superfluid comprises a major component with a full-gap feature instead of a nodal-like pairing symmetry as revealed by specific-heat and lower-critical-field measurements. Combining with resistivity (rho(xx) and rho(xy)) and electronic band-structure calculation, the superconducting and normal-state physical parameters were determined by a self-consistent analysis. It is found that Ru7B3 may belong to a single band superconductor with energy gap of 0.5 meV and could be categorized into type-II superconductor with weak electron-phonon coupling. An unusual "kink" feature is clearly observed in the field induced broadening of the resistivity curves. Possible reasons are given for this unusual two-step transition. |
