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…
Microwave-free wide-field magnetometry using nitrogen-vacancy centers
Joseph Shaji Rebeirro, Muhib Omar, Till Lenz +4
A wide-field magnetometer utilizing nitrogen-vacancy (NV) centers in diamond that does not require microwaves is demonstrated. It is designed for applications where microwaves need…
Electrical readout microwave-free sensing with diamond
Huijie Zheng, Jaroslav Hruby, Emilie Bourgeois +6
While nitrogen-vacancy (NV-) centers have been extensively investigated in the context of spin-based quantum technologies, the spin-state readout is conventionally performed optica…
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…
Rapid online solid-state battery diagnostics with optically pumped magnetometers
Yinan Hu, Geoffrey Z. Iwata, Lykourgos Bougas +7
Solid state battery technology is motivated by the desire to deliver flexible power storage in a safe and efficient manner. The increasingly widespread use of batteries from mass-p…
Battery Diagnostics with Sensitive Magnetometry
Yinan Hu, Geoffrey Z. Iwata, Mohaddese Mohammadi +5
The ever-increasing demand for high-capacity rechargeable batteries highlights the need for sensitive and accurate diagnostic technology for determining the state of a cell, for id…
Microwave-free vector magnetometry with nitrogen-vacancy centers along a single axis in diamond
Huijie Zheng, Zhiyin Sun, Georgios Chatzidrosos +8
Sensing vector magnetic fields is critical to many applications in fundamental physics, bioimaging, and material science. Magnetic-field sensors exploiting nitrogen-vacancy (NV) ce…
Zero-field magnetometry based on nitrogen-vacancy ensembles in diamond
Huijie Zheng, Jingyan Xu, Geoffrey Iwata +10
Ensembles of nitrogen-vacancy (NV) centers in diamonds are widely utilized for magnetometry, magnetic-field imaging and magnetic-resonance detection. They have not been used for ma…
Nondestructive in-line sub-picomolar detection of magnetic nanoparticles in flowing complex fluids
Lykourgos Bougas, Lukas D. Langenegger, Carlos A. Mora +5
Over the last decades, the use of magnetic nanoparticles in research and commercial applications has increased dramatically. However, direct detection of trace quantities remains a…
