Description
Superconducting fluctuations above the critical temperature provide valuable insight in the pairing mechanisms of superconductivity. The recent discovery of a pseudogap phase in NbN has opened many new questions. In this study we measure the paraconductivity and the Hall effect response in NbN originating from superconducting fluctuations. These experimental results are compared to a recent theoretical study on the influence of superconducting fluctuations on the Hall response. The presented study demonstrates experimentally how Gaussian fluctuations of superconductivity contribute to the conductivity tensor.
