Abstract
Cryogenic scanning tunneling microscopy and magnetization measurements were used to study the superconducting properties of The magnetization measurements show a sharp superconductor transition at in agreement with previous works. The tunneling spectra exhibit BCS-like gap structures, with gap parameters in the range of 5 to 7 meV, yielding a ratio of This suggests that is a conventional BCS s-wave superconductor, either in the weak-coupling or in the “intermediate-coupling” regime.
