Nodal multigap superconductivity in KCa2Fe4As4F2
- Abstract:
-
We find evidence that the newly discovered Fe-based superconductor KCa2Fe4As4F2(Tc=33.36(7) K) displays multigap superconductivity with line nodes. Transverse field muon spin rotation (μSR) measurements show that the temperature dependence of the superfluid density does not have the expected behavior of a fully gapped superconductor, due to the lack of saturation at low temperatures. Moreover, the data cannot be well fitted using either single band models or a multiband s-wave model, yet are ...
