Weak-link behavior of grain boundaries in superconducting Ba(Fe1-xCox)2As2 bicrystals
S. Lee, J. Jiang, J. D. Weiss +17
We show that despite the low anisotropy, strong vortex pinning and high irreversibility field Hirr close to the upper critical field Hc2 of Ba(Fe1-xCox)2As2, the critical current d…
Improved properties of epitaxial YNixMn1-xO3 films by annealing under high magnetic fields
Yanwei Ma, Aixia Xu, Xiaohang Li +4
The effect of annealing under a magnetic field on the microstructure and properties of YNixMn1-xO3 (x=0.33 and 0.5) films has been investigated. It is found that the ferromagnetic…
Enhanced critical current density of MgB2 superconductor synthesized in high magnetic fields
Yanwei Ma, Aixia Xu, Xianping Zhang +3
The effect of high magnetic fields on the current carrying properties of both MgB2 bulks and Fe-sheathed tapes was investigated following different thermal sequences. It is found t…
Effect of nano-C doping on the in-situ processed MgB2 tapes
Xianping Zhang, Yanwei Ma*, Aixia Xu +6
The effect of nano-C doping on the microstructure and superconducting properties of Fe-sheathed MgB2 tapes prepared through the in-situ powder-in-tube method was studied. Heat trea…
