On the robustness of the NV-NMR spectrometer setup to magnetic field inhomogeneities [PDF]
Phys. Rev. Lett. 125, 110502 (2020), 2020 The NV-NMR spectrometer is a promising candidate for detection of NMR signals at the nano scale. Field inhomogeneities, however, are a major source of noise that limits spectral resolution in state of the art NV - NMR experiments and constitutes a major bottleneck in the development of nano scale NMR.
