Figure 6

(a) Response of the magnetometer to a 50-ms 2-μGrms square pulse of the oscillating magnetic field tuned in resonance with the Larmor frequency. The traces show raw photodiode signals (without demodulation) recorded for different light powers. (b) Bandwidth of the AC magnetometer determined based on the NMOR resonance while scanning the AC-field frequency around the Larmor frequency. Error bars (smaller than measurement points) represent statistical error obtained via fitting complex Lorentzian to the resonance curves. (c) Rise time of the magnetometer determined from the decay of the rotation signal at the end of a pulse (1/e point).
