Broadband magnetometry by infrared-absorption detection of nitrogen-vacancy ensembles in diamond
V. M. Acosta, E. Bauch, A. Jarmola +3
We demonstrate magnetometry by detection of the spin state of high-density nitrogen-vacancy ensembles in diamond using optical absorption at 1042 nm. With this technique, measureme…
Optical properties of the nitrogen-vacancy singlet levels in diamond
V. M. Acosta, A. Jarmola, E. Bauch +1
We report measurements of the optical properties of the 1042 nm transition of negatively-charged Nitrogen-Vacancy (NV) centers in type 1b diamond. The results indicate that the upp…
Search for plant biomagnetism with a sensitive atomic magnetometer
Eric Corsini, Victor Acosta, Nicolas Baddour +6
We report what we believe is the first experimental limit placed on plant biomagnetism. Measurements with a sensitive atomic magnetometer were performed on the Titan arum (Amorphop…
Rubidium dimers in paraffin-coated cells
V. M. Acosta, A. Jarmola, D. Windes +7
Measurements were made to determine the density of rubidium dimer vapor in paraffin-coated cells. The number density of dimers and atoms in similar paraffin-coated and uncoated cel…
