Quantum sensors take advantage of the extreme sensitivity of quantum systems to external perturbations to accurately measure a broad range of physical quantities. Among a wide variety of quantum systems employed for sensing purposes, the nitrogen-vacancy (NV) defect in diamond has garnered considerable attention in the last decade for the development of highly sensitive magnetometers.
The main focus of the team is devoted to the use of these NV-based sensors, enabling non-invasive, quantitative and vectorial magnetic field imaging with an unprecedented combination of nanoscale spatial resolution and ultrahigh magnetic sensitivity. These unique capabilities are applied to explore exotic spin textures in magnetic nanostructures and to tackle fundamental problems in condensed matter physics at room temperature and in cryogenic environments, with a particular focus on antiferromagnets, ferrimagnets and 2D magnetic materials.
We also explore the use of spin defects in hexagonal boron nitride flakes for implementing flexible and transferable magnetic field wide-field imagers.
