Quantum Diamond Microscope for Geosciences and Electronics

POSTER

Abstract

We present a 'quantum diamond microscope' (QDM) that uses nitrogen-vacancy (NV) defects in diamond for imaging magnetic fields with micron-scale spatial resolution and mm-scale field-of-view for a range of studies in both geosciences and electronics. For the geosciences, the QDM allows us to spatially resolve different ferromagnetic minerals within a rock sample. This capability enables the paleomagnetic study of samples with complex, heterogeneous magnetization, thereby greatly expanding the range of broader scientific questions that can be addressed. For electronics, we can non-invasively monitor the activity of microwave electronics with higher spatial resolution, which is important for moving towards localizing the current flow down to the individual circuit component level.
