Doping Dependence of Upper Critical Field of High-Tc Cuprate Bi2+xSr2-xCaCu2O8+d Estimated from Irreversibility Field at Zero Temperature
Junichiro Kato, Shigeyuki Ishida, Tatsunori Okada +12
We investigated the temperature (T) dependence of the irreversibility field Hirr(T) in high-critical-temperature cuprate Bi2+xSr2-xCa1-yYyCu2O8+d (Bi-2212) single crystals over a w…
Evaluation of Doppler shifts in -wave superconductor tunneling junctions
Takashi Sakamori, Kenki Matsuoka, Mitsuhiro Teshigawara +4
The energy levels of quasiparticles in superconductors experience Doppler shifts due to the influence of a finite current flow. The influence of the Doppler shift is particularly p…
Magnetic field dependence of critical currents of cross-type Josephson junctions with inhomogeneous critical current density under oblique magnetic fields
Soma Haraoka, Edmund Soji Otabe, Yasunori Mawatari
Studies of the magnetic interference of sandwich-type Josephson junctions in which perpendicular or oblique magnetic fields are applied to the junction plane have received less att…
Ginzburg-Landau simulations of three-terminal operation of a superconducting nanowire cryotron
Naoki Yasukawa, Taichiro Nishio, Yasunori Mawatari
Superconducting nanowire cryotrons (nTrons) are expected to be used as interfaces for super-high-performance hybrid devices in which superconductor and semiconductor circuits are c…
