(color online) Schematic diagram of the energy level during the ESR or EDSR measurement. It consists of initialization, spin blockade, spin manipulation, projection, and readout. Spin-flip is achieved in the spin manipulation step by hyperfine interaction,[8,104] spin–orbit interaction,[105] inhomogeneous magnetic field,[106] and g-factor tensor modulation.[107]
