Enhancement of Critical Current Densities in (Ba,K)Fe2As2 by 320 MeV Au Irradiation in Single Crystals and by High-Pressure Sintering in PIT Wires
Sunseng Pyon, Toshihiro Taen, Fumiaki Ohtake +7
We demonstrate a large enhancement of critical current density (Jc) up to 1.0x10^7 A/cm2 at 5 K under self-field in (Ba,K)Fe2As2 single crystals by irradiating 320 MeV Au ions. Wit…
Magnetic relaxation and collective vortex creep in FeTeSe single crystal
Yue Sun, Toshihiro Taen, Yuji Tsuchiya +3
We study the vortex dynamics in high-quality FeTeSe single crystal by performing magnetization measurements of the screening current density \emph{J} and flux c…
Evolution of Superconductivity in FeTeSe Annealed in Te Vapor
Yue Sun, Yuji Tsuchiya, Tatsuhiro Yamada +4
We report a detailed study of the Te vapor annealing effect in FeTeSe single crystals. Bulk superconductivity can be gradually induced by annealing with inc…
Flux avalanches in Nb superconducting shifted strip arrays
Y. Tsuchiya, Y. Mawatari, J. Ibuka +6
Flux penetrations into three-dimensional Nb superconducting strip arrays, where two layers of strip arrays are stacked by shifting a half period, are studied using a magneto-optica…
Large, Homogeneous, and Isotropic Critical Current Density in Oxygen-Annealed Fe1+yTe0.6Se0.4 Single Crystal
Yue Sun, Toshihiro Taen, Yuji Tsuchiya +4
We reported a controllable way of removing excess Fe in Fe1+yTe0.6Se0.4 by annealing in a fixed amount of O2. Compared with the weak superconductivity induced by dilute acids, O2 a…
