High transport Jc in magnetic fields up to 28 T of stainless steel/Ag double sheathed Ba122 tapes fabricated by scalable rolling process
Zhaoshun Gao, Kazumasa Togano, Akiyoshi Matsumoto +1
The recently discovered iron-based superconductors with very high upper critical field and small anisotropy have been regarded as a potential candidate material for high field appl…
Achievement of practical level critical current densities in PIT Ba1-xKxFe2As2/Ag tapes by conventional cold mechanical deformation
Zhaoshun Gao, Kazumasa Togano, Akiyoshi Matsumoto +1
We found that transport critical current density (Jc) of the Ba1-xKxFe2As2/Ag tapes is significantly enhanced by the combination process of cold flat rolling and uniaxial pressing.…
Large enhancement of transport critical current density of ex-situ PIT Ag/(Ba,K)Fe2As2 tapes achieved by applying cycles of cold deformation and heat treatment
Kazumasa Togano, Zhaoshun Gao, Akiyoshi Matsumoto adn Hiroaki Kumakura
We report that high transport critical current density exceeding 104 A/cm2 at 4.2 K and 10 T can be obtained with good reproducibility for Ag sheathed (Ba,K)Fe2As2 (Ba 122) tapes b…
High critical current density and low anisotropy in textured Sr1-xKxFe2As2 tapes for high field applications
Zhaoshun Gao, Yanwei Ma, Chao Yao +5
From the application point of view, large critical current densities Jc (H) for superconducting wires are required, preferably for magnetic fields higher than 5 T. Here we show tha…
Enhanced high-field transport critical current densities observed for the ex-situ PIT processed Ag/(Ba,K)Fe2As2 thin tapes
K. Togano, Z. S. Gao, H. Taira +6
We found that the transport Jc of the ex-situ PIT processed (Ba,K)Fe2As2 (Ba-122) wire with single Ag sheath can be significantly enhanced by repeating the combined process of roll…
Calculation of the transport critical current density of c-axis textured 122 iron-based superconductors
Lei Wang, Jinghui Xu, Duoduo Ba +4
The c-axis textured Sr1-xKxFe2As2 tapes produced by cold rolling and post-annealing, could carry a high super-current over 2*104 A/cm2. However, the magnitude is far from its maxim…
