Zero- to low-field J-spectroscopy with a diamond magnetometer
Muhib Omar, Jingyan Xu, Raphael Kircher +8
We report measurements of zero- to ultra-low-field nuclear magnetic resonance (ZULF NMR) signals at frequencies of a few hertz with a diamond-based magnetic sensor. The sensing dia…
Diamond-optic enhanced photon collection efficiency for sensing with nitrogen-vacancy centers
Muhib Omar, Andreas Conta, Andreas Westerhoff +4
We present a design to increase the amount of collected fluorescence emitted by nitrogen-vacancy color centers in diamond used for quantum-sensing. An improvement was measured in c…
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…
Battery characterization via eddy-current imaging with nitrogen-vacancy centers in diamond
Xue Zhang, Georgios Chatzidrosos, Yinan Hu +4
Sensitive and accurate diagnostic technologies with magnetic sensors are of great importance for identifying and localizing defects of rechargeable solid batteries in a noninvasive…
Probing topological spin structures using light-polarization and magnetic microscopy
Till Lenz, Georgios Chatzidrosos, Zhiyuan Wang +12
