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…
Systematic characterization of nanoscale -BN quantum sensor spots created by helium-ion microscopy
Hao Gu, Moeta Tsukamoto, Yuki Nakamura +8
The nanosized boron vacancy () defect spot in hexagonal boron nitride (-BN) is promising for a local magnetic field quantum sensor. One of its advantages is that…
Optical-power-dependent splitting of magnetic resonance in nitrogen-vacancy centers in diamond
Shuji Ito, Moeta Tsukamoto, Kensuke Ogawa +3
Nitrogen-vacancy (NV) centers in diamonds are a powerful tool for accurate magnetic field measurements. The key is precisely estimating the field-dependent splitting width of the o…
Magnetic field imaging by hBN quantum sensor nanoarray
Kento Sasaki, Yuki Nakamura, Hao Gu +8
Placing a sensor close to the target at the nano-level is a central challenge in quantum sensing. We demonstrate high-spatial-resolution magnetic field imaging with a boron vacancy…
