Abstract
This paper demonstrates a high-field spin magnetometer using hyperpolarized ¹³C nuclear spins in diamond, initialized by Nitrogen Vacancy (NV) centers. The ¹³C spins are protected along a transverse Bloch sphere axis for extended periods, allowing detection of time-varying magnetic fields with a bandwidth up to 7 kHz, spectral resolution <100 mHz, and single-shot sensitivity of 410 pT/√Hz at 7T. This approach offers opportunities for microscale NMR chemical sensors and applications in high-resolution magnetometry.
