Spin qubits based on diamond NV centers can detect tiny magnetic fields; thin two-dimensional materials produce tiny magnetic fields. Do they make a good match? I will discuss two works that explored how NV magnetometry can uniquely probe the spins and currents in crystals that are one-atom thick.
How we discovered, via local magnetic noise measurements, that graphene electrons at high bias undergo cherenkov radiation of phonons
How we performed the first NMR measurement on a single-atom thick crystal.
Some thoughts and outlook on the benefits and challenges of using spin qubits to measure condensed matter systems.
