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 detection and control of individual Abrikosov vortices in superconducting microwave resonators. resonators with a narrowed region near the grounded end ac…
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.…
