Fig. 4: Spin population of ms = 0 state of the first cluster at B = 800 G.

The decoherence is taken into account based on (a) Model 1, (b) Model 2 with 47 nitrogen and 48 boron atom clusters, respectively, (c) Model 3 \({{\rm{T}}}_{2}^{* }=200\) ns and 47 nitrogen and 48 boron atom clusters, and (d) Model 4 with 28 nitrogen atom clusters. The T1 time is obtained from fitting \({e}^{(-{(t/{T}_{1})}^{n})}\) + y0.
