Figure 5: Calibrating Bz-dependent nuclear polarization.
(a,b) Normalized photoluminescence (P.L.) plotted as a function of the magnetic driving field carrier frequency for (a) Bz=20.2 G and (b) Bz=171.5 G. The solid line in each plot is a least squares fit to the sum of three Lorentzians. The data in a,b was measured on a single device with an NV centre ensemble, and error bars are from the s.d. in photon counting. (c) Normalized amplitude of each mI hyperfine sublevel as a function of Bz. The solid lines are least squares fits to a linear model, each point corresponds to a single measurement, and error bars are standard error from the fits.
