Spectroscopic evidence of mixed angular momentum symmetry in non-centrosymmetric Ru$_7$B$_3
Superconducting crystals with lack of inversion symmetry can potentially host unconventional pairing. However, till date, no direct conclusive experimental evidence of such unconventional order parameters in non-centrosymmetric superconductors has been reported. In this paper, through direct measure...

| description | Superconducting crystals with lack of inversion symmetry can potentially host
unconventional pairing. However, till date, no direct conclusive experimental
evidence of such unconventional order parameters in non-centrosymmetric
superconductors has been reported. In this paper, through direct measurement of
the superconducting energy gap by scanning tunnelling spectroscopy, we report
the existence of both $s$-wave (singlet) and $p$-wave (triplet) pairing
symmetries in non-centrosymmetric Ru$_7$B$_3$. Our temperature and magnetic
field dependent studies also indicate that the relative amplitudes of the
singlet and triplet components of the order parameter change differently with
temperature. |
