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…
Efficient Conversion of Nitrogen to Nitrogen-Vacancy Centers in Diamond Particles with High-Temperature Electron Irradiation
Yuliya Mindarava, Rémi Blinder, Christian Laube +9
Fluorescent nanodiamonds containing negatively-charged nitrogen-vacancy (NV) centers are promising for a wide range of applications, such as for sensing, as fluorescence biomar…
Photoluminescence at the ground state level anticrossing of the nitrogen-vacancy center in diamond
Viktor Ivády, Huijie Zheng, Arne Wickenbrock +9
The nitrogen-vacancy center (NV center) in diamond at magnetic fields corresponding to the ground state level anticrossing (GSLAC) region gives rise to rich photoluminescence (PL)…
