a Schematic of the measurement sequence to electrically control nitrogen vacancy (NV) Rabi frequency. b The time-dependent photoluminescence intensity of NV1 measured at Jc = 0 and ±1 × 1011 A/m2. c Normalized NV Rabi frequency \(f_{{\mathrm{Rabi}}}/\sqrt P\) measured as a function of \(f_ - - f_{{\mathrm{FMR}}}\). The green, blue, and red curves correspond to Jc = 0 and ±1 × 1011 A/m2, respectively. d When \(f_ - = f_{{\mathrm{FMR}}}\), the measured current density dependence of \(f_{{\mathrm{Rabi}}}/\sqrt P\) (red points) agrees well with the theoretical prediction based on the spin-orbit-torque-model (blue line).
