Tunneling spectra of break junctions involving Nb₃Sn
The electronic gap structure of Nb3Sn was measured by the break-junction (BJ) tunneling technique. The superconducting
 gap values are estimated to be in the range 2∆ = 4–5.5 meV at T = 4.2 K as follows from the observed
 distinct conductance peaks. In addition to the superconducting...

| description | The electronic gap structure of Nb3Sn was measured by the break-junction (BJ) tunneling technique. The superconducting
gap values are estimated to be in the range 2∆ = 4–5.5 meV at T = 4.2 K as follows from the observed
distinct conductance peaks. In addition to the superconducting gap structure, we observed reproducible
hump-like structures at the biases of about ± 20 and ± 50 mV. Such a coexistence of gap and hump structures resembles
the situation found in the high-Tc copper-oxide superconductors. Above the superconducting critical
temperature Tc ~ 18 K, the humps appear as the only gap-like structures. Their possible origin is discussed in
connection to the structural phase transition occurring in Nb₃Sn.
