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…
High-performance Ba1-xKxFe2As2 superconducting joints for persistent current operation
Yanchang Zhu, Dongliang Wang, Qiqi Wang +7
Superconducting joints are one of the key technologies to make Ba1-xKxFe2As2 (Ba-122) superconducting wires or tapes for high-field applications. Herein, superconducting joints wer…
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…
Chemical stability and superconductivity in Ag-sheathed CaKFe4As4 superconducting tapes
Zhe Cheng, Chiheng Dong, He Huang +7
Ag-sheathed CaKFe4As4 superconducting tapes have been fabricated via the ex-situ powder-in-tube method. Thermal and X-ray diffraction analyses suggest that the CaKFe4As4 phase is u…
Superconducting joint between iron-based superconductor tapes
Yanchang Zhu, Dongliang Wang, Chundong Zhu +5
Superconducting joints are essential for iron-based superconductor's applications in future. In this study, a process for fabricating superconducting joints between Sr1-xKxFe2As2 (…
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…
