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…
Observation of chiral domain walls in an octupole-ordered antiferromagnet
Moeta Tsukamoto, Zhewen Xu, Tomoya Higo +10
Spin chirality in antiferromagnets offers new opportunities for spintronics. The kagome antiferromagnet Mn3Sn is a paradigmatic material in which the antiferromagnetic order parame…
Investigations of optical aberration on quantum diamond microscopy toward high spatial resolution and sensitivity
Shunsuke Nishimura, Moeta Tsukamoto, Kento Sasaki +1
Quantum diamond microscopy (QDM), which employs nitrogen-vacancy (NV) center ensembles, is a promising approach to quantitatively imaging magnetic fields with both high resolution…
