Nanodiamond quantum thermometry assisted with machine learning
Kouki Yamamoto, Kensuke Ogawa, Moeta Tsukamoto +3
Nanodiamonds (NDs) are quantum sensors that enable local temperature measurements, taking advantage of their small size. Though the model based analysis methods have been used for…
Quantitative imaging of nonlinear spin-wave propagation using diamond quantum sensors
Kensuke Ogawa, Moeta Tsukamoto, Yusuke Mori +7
Spin waves propagating in magnetic materials exhibit nonlinear behavior at large amplitudes due to the competition between excitation and relaxation, providing an attractive platfo…
Wideband wide-field imaging of spin-wave propagation using diamond quantum sensors
Kensuke Ogawa, Moeta Tsukamoto, Yusuke Mori +6
Imaging spin-wave propagation in magnetic materials in a wide frequency range is crucial for understanding and applying spin-wave dynamics. Recently, nitrogen-vacancy (NV) centers…
Demonstration of highly-sensitive wideband microwave sensing using ensemble nitrogen-vacancy centers
Kensuke Ogawa, Shunsuke Nishimura, Kento Sasaki +1
Microwave magnetometry is essential for the advancement of microwave technologies. We demonstrate a broadband microwave sensing protocol using the AC Zeeman effect with ensemble ni…
