In-gap quasiparticle excitations induced by non-magnetic Cu impurities in Na(Fe(0.96)Co(0.03)Cu(0.01))As revealed by scanning tunnelling spectroscopy
The origin of superconductivity in the iron pnictides remains unclear. One suggestion is that superconductivity in these materials has a magnetic origin, which would imply a sign-reversal s(±) pairing symmetry. Another suggests it is the result of orbital fluctuations, which would imply a sign-equal...
