Nanoscale magnetic imaging using single spins in diamond

The nitrogen-vacancy (NV) center in diamond has emerged as an exceptional system for a variety of sensing applications in areas ranging from mesoscopic physics to materials science and biology.  A single electronic spin localized to the NV defect is sensitive to physical quantities such as magnetic and electric fields, pressure, and temperature, and offers nanometer-scale spatial resolution with stable, robust operation over a wide temperature range. I will present an overview of our work in Basel, which focuses on magnetic imaging with an NV center embedded in a diamond AFM probe, enabling quantitative imaging of magnetic fields with a spatial resolution of tens of nanometers.
