It becomes more challenging when magnetic fields are present, because the field distribution, the electron density of states, and the superconducting pairing potentials are nonuniform. Here we present tunneling microspectroscopic experiments on NbC single crystals and show that NbC is a homogeneous dirty superconductor. When applying magnetic fields to the sample, we observe that the zero-energy local density of states and the pairing energy gap follow an explicit scale rel","authors_text":"Chang-Jiang Yi, Chang-Jiang Zhu, Han-Bin Deng, Jia-Xin Yin, Limin Liu, Peng-Bo Song, R.
