Robust High-Dynamic-Range Vector Magnetometry via Nitrogen-Vacancy Centers in Diamond

, 2018
We demonstrate a robust, scale-factor-free vector magnetometer, which uses a closed-loop frequency-locking scheme to simultaneously track Zeeman-split resonance pairs of nitrogen-vacancy (NV) centers in diamond.

Pump-Enhanced Continuous-Wave Magnetometry using Nitrogen-Vacancy Ensembles [PDF]

, 2017
Ensembles of nitrogen-vacancy centers in diamond are a highly promising platform for high-sensitivity magnetometry, whose efficacy is often based on efficiently generating and monitoring magnetic-field dependent infrared fluorescence.

Magnetic hallmarks of viscous electron flow in graphene

, 2019
We propose a protocol to identify spatial hallmarks of viscous electron flow in graphene and other two-dimensional viscous electron fluids. We predict that the profile of the magnetic field generated by hydrodynamic electron currents flowing in confined ...
