Characterizing the nitrogen-vacancy center singlet transition and its phonon sideband for absorption-based room-temperature magnetometry
Tobias Probst, Florian Schall, Sebastian Heuft +9
Magnetometry with nitrogen-vacancy (NV) centers in diamond has shown great promise in recent years. In particular, absorption-based magnetometry techniques, employing a cavity to e…
A robust laser cavity platform for NV-diamond singlet infrared absorption magnetometry
Shao Qi Lim, Alexander A. Wood, Brett C. Johnson +9
The negatively charged nitrogen-vacancy center (NV) in diamond is a versatile platform for quantum magnetometry under ambient conditions. Recently, laser threshold magnetometry…
Laser-enhanced quantum sensing boosts sensitivity and dynamic range
Florian Schall, Lukas Lindner, Yves Rottstaedt +8
Magnetometers based on nitrogen-vacancy (NV) centers in diamond have emerged as the most important solid-state quantum sensors. However, ensembles are limited in optical contrast t…
Spin coherence in strongly coupled spin baths in quasi-two-dimensional layers
Philip Schätzle, Reyhaneh Ghassemizadeh, Daniel F. Urban +5
We investigate the spin-coherence decay of NV-spins interacting with the strongly-coupled bath of nitrogen defects in diamond layers. For thin diamond layers, we demonstrate th…
