The nitrogen-vacancy (NV) center is an atomic-scale defect in diamond. It hosts an electronic spin that can be initialized and detected optically, making it an exceptional system for quantum sensing of magnetic phenomena at room temperature. A particularly powerful approach is to incorporate the NV center in a scanning probe microscope (SPM), which enables a unique combination of field sensitivity with nanometric spatial resolution.

During this webinar, we will present the Qnami ProteusQ, the first commercial SPM making use of NV quantum technology. Specifics of this quantum microscope, which enable quantitative and non-perturbative analysis of surface magnetic fields, will be discussed. We will demonstrate the performance of this new characterization tool through magnetometry on antiferromagnetic systems and ultra-thin ferromagnets.
