Condensed Matter/Materials & Biological Physics Seminar with Andy Mounce on Nanoscale Magnetometry

The properties that make nitrogen-vacancies in diamond (NVs) good qubits (for example long coherence times at room temperature) make them even better quantum sensors of magnetic fields. In this presentation, I will discuss the properties of NVs and how to utilize them for detecting magnetic fields of devices and materials from static magnetic fields and to fluctuating fields up to GHz frequencies. At the Center for Integrated Nanotechnologies, (a DoE funded nano-science research center) we have a user program to enable NV quantum sensing through integration, fabrication, ion implantation, and development of measurement capabilities. In this presentation, I will discuss three aspects of our work: improving NV sensitivity, imaging static and dynamic magnetic fields with widefield magnetometry, and using NV for sensing magnetic properties of low dimensional quantum materials.
