Event Details

The nitrogen vacancy (NV) center in diamond is an atomic-scale defect that exhibits remarkably coherent quantum properties in a uniquely accessible way: over a wide range of temperatures (1K-300K) and in ambient and high vacuum conditions. By incorporating the NV center into a scanning probe microscope geometry, we have demonstrated a powerful tool for imaging nanoscale magnetism in condensed matter systems [1]. Here I discuss two novel functionalities of the NV center afforded by its unique nature as a quantum sensor. I present NV-based conductivity imaging on the nanoscale in a quantitative and noninvasive way [2]. We also extend recently developed NV sensing techniques to simultaneously probe both the nanoscale structure and fluctuation dynamics of skyrmions in a thin-film system.
