Nuclear magnetic resonance spectroscopy (NMR) and magnetic resonance imaging (MRI) are powerful analysis tools in life science and medicine. The sensitivity of both depends critically on the nuclear spin polarisation. Dynamical nuclear polarization of C13 nuclear spins in diamond via optically pumped Nitrogen-Vacancy centers (NV) allow a high degree of polarization to be reached even at room temperature and low magnetic field.
Here we compare different polarization schemes in terms of their efficiency and robustness against magnetic field misalignment, which is of crucial importance for their application to randomly oriented nanodiamonds. In contrast to ensemble measurements, the single spin approach allows us to investigate the characteristics of a single nuclear spin bath surrounding a NV.
