DYSCO magnetometry and dynamic range enhancements. (a) Schematic and (b) experimental results of magnetic sensing obtained without |2π| ambiguity by controlling the dynamical sensitivity of the NV spin. (c) Results depicting the extent of the dynamic range (4 · 103) achieved using DYSCO. The lower bound is obtained by setting β = 1 (blue curve), whereas β = 0 (yellow curve) provides an upper bound for the DR. (d) Precision magnetometry performed at t N = 1.92 ms total acquisition time using an NV spin present in a natural abundance 1.1% 13C diamond.
