Electronic spins associated with the Nitrogen-Vacancy (NV) center in diamond offer an opportunity to study spin-related phenomena with extremely high sensitivity owing to their high degree of optical polarization. It can be operated from cryogenic temperatures to above room temperature, has a dynamic range spanning from direct current to gigahertz and allows sensor–sample distances as small as a few nanometres. As such, NV magnetometry provides access to static and dynamic magnetic and electronic phenomena with nanoscale spatial resolution.
The talk will primarily revolve around various modalities of magnetometry utilizing NV centers, including scanned probe imaging and widefield imaging using bulk NV diamond. Different pulse protocols will be examined, highlighting their impact on sensitivity and precision in measuring magnetic signals challenges associated with controlling and manipulating NV centers, as well as strategies for mitigating environmental influences to ensure reliable and accurate measurements.
