Variable single-axis magnetic-field generator using permanent magnets
Oleg Tretiak, Peter Blümler, Lykourgos Bougas
We present a design for producing precisely adjustable and alternating single-axis magnetic fields based on nested Halbach dipole pairs consisting of permanent magnets only. Our de…
Infrared laser magnetometry with a NV doped diamond intracavity etalon
Yannick Dumeige, Jean-François Roch, Fabien Bretenaker +8
We propose an hybrid laser system consisting of a semiconductor external cavity laser associated to an intra-cavity diamond etalon doped with nitrogen-vacancy color centers. We con…
Eddy-current imaging with nitrogen-vacancy centers in diamond
Georgios Chatzidrosos, Arne Wickenbrock, Lykourgos Bougas +4
We demonstrate microwave-free eddy-current imaging using nitrogen-vacancy centers in diamond. By detecting the eddy-current induced magnetic field of conductive samples, we can dis…
Diamond magnetic microscopy of malarial hemozoin nanocrystals
Ilja Fescenko, Abdelghani Laraoui, Janis Smits +6
Magnetic microscopy of malarial hemozoin nanocrystals was performed using optically detected magnetic resonance imaging of near-surface diamond nitrogen-vacancy centers. Hemozoin c…
Sawtooth wave adiabatic passage slowing of dysprosium
Niels Petersen, Florian Mühlbauer, Lykourgos Bougas +3
We report on sawtooth wave adiabatic passage (SWAP) slowing of bosonic and fermionic dysprosium isotopes by using a 136 kHz wide transition at 626 nm. A beam of precooled atoms is…
Widefield imaging of superconductor vortices with electron spins in diamond
Yechezkel Schlussel, Till Lenz, Dominik Rohner +11
Understanding the mechanisms behind high- Type-II superconductors (SC) is still an open task in condensed matter physics. One way to gain further insight into the microscopi…
Nondestructive in-line sub-picomolar detection of magnetic nanoparticles in flowing complex fluids
Lykourgos Bougas, Lukas D. Langenegger, Carlos A. Mora +5
Over the last decades, the use of magnetic nanoparticles in research and commercial applications has increased dramatically. However, direct detection of trace quantities remains a…
