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…
