Tailored joint fabrication process derived ultra-low resistance MgB2 superconducting joint
Dipak Patel, Akiyoshi Matsumotoa, Hiroaki Kumakura +5
We report an ultra-low resistance superconducting joint using unreacted multifilament MgB2 wires produced by tailoring the powder compaction pressure within the joint with heat tre…
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…
Large transport critical currents and magneto-optical imaging of textured Sr1-xKxFe2As2 superconducting tapes
Yanwei Ma, Chao Yao, Xianping Zhang +7
We report the temperature dependence of the transport critical current density (Jc) in textured Sr1-xKxFe2As2/Fe (Sr122) tapes fabricated by an ex situ powder-in-tube process. Crit…
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…
