Integrated and portable magnetometer based on nitrogen-vacancy ensembles in diamond
Felix M. Stürner, Andreas Brenneis, Thomas Buck +13
Magnetic field sensors that exploit quantum effects have shown that they can outperform classical sensors in terms of sensitivity enabling a range of novel applications in future,…
Diamond magnetometry and gradiometry towards subpicotesla DC field measurement
Chen Zhang, Farida Shagieva, Matthias Widmann +11
Nitrogen vacancy (NV) centers in diamond have developed into a powerful solid-state platform for compact quantum sensors. However, high sensitivity measurements usually come with a…
Imaging damage in steel using a diamond magnetometer
L. Q. Zhou, R. L. Patel, A. C. Frangeskou +6
We demonstrate a simple, robust and contactless method for non-destructive testing of magnetic materials such as steel. This uses a fiber-coupled magnetic sensor based on nitrogen…
Heterodyne Sensing of Microwaves with a Quantum Sensor
Jonas Meinel, Vadim Vorobyov, Boris Yavkin +5
Diamond quantum sensors are sensitive to weak microwave magnetic fields resonant to the spin transitions. However the spectral resolution in such protocols is limited ultimately by…
