a Rabi oscillation of Defect A. The inset schematically shows the pulse sequence, in which the first excitation laser pulse is used for the initialization of the spin state and the second pulse is used for a readout of the state after the MW pulse. b Spin-lattice relaxation time (T1) measurement of Defect A. The inset schematically shows the pulse sequence, in which the duration of the MW π-pulse is obtained from Rabi oscillation and the waiting time τ is varied. We can obtain the fitted T1 = 16.17 ± 1.55 μs. c Hahn-echo experiment of Defect A. The inset schematically shows the pulse sequence. We can obtain the fitted T2 = 2.45 ± 0.41 μs. All measurements are performed under a 35.8-mT magnetic field at room temperature.
