Fiberized diamond-based vector magnetometers
Georgios Chatzidrosos, Joseph Shaji Rebeirro, Huijie Zheng +10
We present two fiberized vector magnetic-field sensors, based on nitrogen-vacancy (NV) centers in diamond. The sensors feature sub-nT/ magnetic sensitivity. We…
Eddy-current imaging with nitrogen-vacancy centers in diamond
Georgios Chatzidrosos, Arne Wickenbrock, Lykourgos Bougas +4
We demonstrate microwave-free eddy-current imaging using nitrogen-vacancy centers in diamond. By detecting the eddy-current induced magnetic field of conductive samples, we can dis…
Miniature cavity-enhanced diamond magnetometer
Georgios Chatzidrosos, Arne Wickenbrock, Lykourgos Bougas +5
We present a highly sensitive miniaturized cavity-enhanced room-temperature magnetic-field sensor based on nitrogen-vacancy (NV) centers in diamond. The magnetic resonance signal i…
Level anti-crossing magnetometry with color centers in diamond
Huijie Zheng, Georgios Chatzidrosos, Arne Wickenbrock +7
Recent developments in magnetic field sensing with negatively charged nitrogen-vacancy centers (NV) in diamond employ magnetic-field (MF) dependent features in the photoluminescenc…
