The longitudinal and transverse components of the rf field can be extracted from the phase acquired during free evolution of the spin coherence. In our experimental demonstration, a single electron spin of an NV center in diamond serves as an atomic size of two components of an rf field.enPhysical review research;5(2)https://creativecommons.org/licenses/by/4.0/Quantum controlQuantum sensingNitrogen vacancy centers in diamond530Article
