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…

Two-media laser threshold magnetometry: A magnetic-field-dependent laser threshold

Yves Rottstaedt, Lukas Lindner, Florian Schall +9

Nitrogen-vacancy (NV) centers in diamond are a promising platform for high-precision magnetometry. In contrast to the use of spontaneous emission in a number of NV-magnetometers, l…

The properties of the nitrogen-vacancy center in milled chemical vapor deposition nanodiamonds

Alessandro Mameli, Giannis Thalassinos, Marco Capelli +14

Fluorescent nanodiamonds (FNDs) containing negatively charged nitrogen-vacancy (NV-) centers are vital for many emerging quantum sensing applications from magnetometry to intracell…

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…
