Local Suppression of Superconductivity in Niobium Films by Focused Silicon Ion Implantation
Rochelle Y. Qu, Shunsuke Nishimura, Max Proepper +8
Magnetic flux trapped in a superconducting circuit shifts the critical currents of nearby Josephson junctions and disturbs the operation of the circuit. The usual remedy is a moat…
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…
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.…
