a, Rabi oscillations as a function of microwave frequency, measured at low microwave power. b, Linecut of the data in a, integrated over the first 100 ns. The presented data are the mean ± one standard deviation; N = 10. c,d, ODMR spectra and Rabi oscillations measured between 0 and 5 mT oriented at an arbitrary angle to the defect z axis. e, ODMR spectrum measured for 3 mT magnetic field orthogonal to the defect z axis. f, ODMR spectrum measured with 20-mT magnetic field parallel to the defect z axis. The shaded curves in e and f are the computed spectra (Supplementary Section 4).
