Diamond quantum-sensing platform with integrated boron-doped diamond microwave antenna and thermometer
Masahiro Ohkuma, Ryo Matsumoto, Shintaro Adachi +5
Wide-field nitrogen-vacancy (NV) magnetic imaging at cryogenic temperatures requires microwave excitation and reliable knowledge of the temperature near the sensing region. Here, w…
Wide-field NV magnetometry under simultaneous high-pressure and high-temperature conditions
Masahiro Ohkuma, Eikichi Kimura, Shumpei Ohyama +7
We demonstrate wide-field optically detected magnetic resonance (ODMR) under simultaneous high-pressure and high-temperature conditions using nitrogen-vacancy (NV) centers. Althoug…
Probing the Meissner effect in single crystals of via wide-field quantum microscopy under high pressure
Masahiro Ohkuma, Ryo Matsumoto, Shintaro Adachi +5
We investigated the pressure dependence of the superconducting transition temperature () in optimally doped BiSrCaCuO (Bi-2223) single crystals…
Absorption and birefringence study for reduced optical losses in diamond with high NV concentration
T. Luo, F. A. Hahl, J. Langer +8
The use of diamond color centers such as the nitrogen-vacancy (NV) center is increasingly enabling quantum sensing and computing applications. Novel concepts like cavity coupling a…
Magnetic-Field-Dependent Stimulated Emission from Nitrogen-Vacancy Centres in Diamond
F. Hahl, L. Lindner, X. Vidal +9
Negatively charged nitrogen-vacancy centres in diamond are promising quantum magnetic field sensors. Laser threshold magnetometry has been a theoretical approach for the improvemen…
