Emerging Widefield Magnetic Microscopy Applications with Nitrogen-Vacancy centers in Diamond

We will discuss using magnetically-sensitive nitrogen-vacancy (NV) color centers in diamond for widefield magnetic microscopy, a technique which offers sub-micron spatial resolution, high magnetic moment sensitivity, and parallel magnetic readout in ambient conditions. NV magnetic imaging is being used to study superconductivity, current flow in 2D materials, magnetic domain structures, and other condensed-matter physics applications. With the objective of exploiting the NV magnetic imaging advantages in a wider array of scientific problems, we will report on our recent progress using NV imaging for applications relating to synthetic micromagnets, magnetic materials, hardware security, and electronics fabrication.
