Wide-field magnetic imaging of shielding-current-driven vortex rearrangement under local heating using diamond quantum sensors
Ryoei Ota, Shunsuke Nishimura, Koki Honda +6
Understanding and controlling vortex motion in superconductors are important both for suppressing dissipation in superconducting devices and for device applications that exploit vo…
Direct imaging of stress tensor around single dislocation in diamond
Takeyuki Tsuji, Shunta Harada, Tokuyuki Teraji
Dislocations are fundamental crystal defects whose stress fields govern a wide range of material properties. The analytical form of the stress tensor around single dislocation was…
Observation of individual vortex penetration in a coplanar superconducting resonator
Kirill Shulga, Shunsuke Nishimura, Pavel A. Volkov +7
We demonstrate the microwave signatures of individual Abrikosov-vortex penetration events in superconducting microwave resonators. resonators with a narrowed region near the…
Visualization of Current-Driven Vortex Formation in High- Cuprate Superconductors
Shunsuke Nishimura, Takeyuki Tsuji, Takayuki Iwasaki +3
Type-II superconductors exhibit hysteretic behavior due to the presence of quantum vortices, and the order in which temperature and external field are varied plays a decisive role.…
Extending spin dephasing time of perfectly aligned Nitrogen-Vacancy centers by mitigating stress distribution on highly misoriented chemical-vapor-deposition diamond
T. Tsuji, T. Sekiguchi, T. Iwasaki +1
Extending the spin-dephasing time (T2*) of perfectly aligned nitrogen-vacancy (NV) centers in large-volume chemical vapor deposition (CVD) diamonds leads to enhanced DC magnetic se…
Wide-field quantitative magnetic imaging of superconducting vortices using perfectly aligned quantum sensors
Shunsuke Nishimura, Taku Kobayashi, Daichi Sasaki +5
Various techniques have been applied to visualize superconducting vortices, providing clues to their electromagnetic response. Here, we present a wide-field, quantitative imaging o…
