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…
Synthesis of -axis textured CaKFeAs superconducting bulk via spark plasma texturing technique
Shigeyuki Ishida, Yoshihisa Kamiya, Yoshinori Tsuchiya +7
Grain alignment is a key factor that determines the performance of a superconducting bulk. In this study, the spark plasma texturing (SPT) technique was used to fabricate a CaKFe$_…
Synthesis of CaKFeAs bulk samples with high critical current density using a spark plasma sintering technique
Shigeyuki Ishida, S. Pavan Kumar Naik, Yoshinori Tsuchiya +7
A high density CaKFeAs bulk sample was successfully synthesized using a spark plasma sintering (SPS) technique. The density of the synthesized sample was 5.02 g cm,…
