Superconducting properties of noncentrosymmetric Nb0.18Re0.82 thin films probed by transport and tunneling experiments

Superconducting thin films of the noncentrosymmetric superconductor Nb0.18Re0.82 were successfully deposited by UHV sputtering technique. X-ray diffraction analysis indicated that the films are polycrystalline, with a preferential (nn0) orientation and the lattice parameter in agreement with the expected single alpha-Mn cubic phase. A detailed electrical characterization of the samples as a function of the thickness (3.5 n
