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…
Superconducting materials: Challenges and opportunities for large-scale applications
Chao Yao, Yanwei Ma
Superconducting materials hold great potential to bring radical changes for electric power and high-field magnet technology , enabling high-efficiency electric power generation, hi…
High-performance Ba1-xKxFe2As2 superconducting tapes with grain texture engineered via a scalable and cost-effective fabrication
Shifa Liu, Chao Yao, He Huang +6
Nowadays the development of high-field magnets strongly relies on the performance of superconducting materials. Iron-based superconductors exhibit high upper critical fields and lo…
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…
