Asymmetric stress engineering of dense dislocations in brittle superconductors for strong vortex pinning
Meng Han, Chiheng Dong, Chao Yao +17
Large lossless currents in high-temperature superconductors (HTS) critically rely on dense defects with suitable size and dimensionality to pin vortices, with dislocations being pa…
First performance test of 30 mm iron-based superconductor single pancake coil under 24 T background field
Dongliang Wang, Zhan Zhang, Xianping Zhang +6
The iron-based superconductor (IBS) single pancake coil (SPC) with 30 mm inner diameter was firstly fabricated and tested under 24 T background field. This SPC was successfully mad…
Calorimetric evidence for enhancement of homogeneity in high performance Sr1-xKxFe2As2 superconductors
Chiheng Dong, Chao Yao, He Huang +3
We comparatively studied the critical current density, magnetization and specific heat of the rolled and the hot-pressed Sr1-xKxFe2As2 tapes. The Schottky anomaly that is obvious i…
High transport current superconductivity in powder-in-tube Ba0.6K0.4Fe2As2 tapes at 27 tesla
He Huang, Chao Yao, Chiheng Dong +6
The high upper critical field and low anisotropy of iron-based superconductors make them being particularly attractive for high-field applications. However, the current carrying ca…
Fabrication and Transport Properties of 100 m Class Sr0.6K0.4Fe2As2 Wires and Pancake Coils
Xianping Zhang, Hidetoshi Oguro, Chao Yao +6
Iron-pnictides are hotly studied since 2008 in the superconducting materials research area, due to their special properties and unclear mechanism. Big achievement has been made in…
Vortex pinning and dynamics in high performance Sr0.6K0.4Fe2As2 superconductor
Chiheng Dong, He Lin, He Huang +7
We have studied vortex pinning and dynamics in a Sr0.6K0.4Fe2As2 superconducting tape with critical current density Jc~0.1 MA/cm2 at 4.2 K and 10 T. It is found that grain boundary…
