Achieving high current superconducting wires for large scale applications and magnets has been one of the most challenging objectives during all the HTS era. Coated conductors of YBa2Cu3O7 (YBCO) have emerged as the most attractive opportunity to achieve unique performances while reducing the cost/performance ratio continues to be a key objective at present. Chemical solution deposition (CSD)...
The Fe-based superconductors (FBS) present a large variety of compounds whose properties, including flux pinning, are affected to different extents by their crystal structures. The doped $AEFe_2As_2$ phases ($AE = Ba,Sr$) mostly show a 3D character similar to low-$T_c$ superconductors and can accept a high density of artificial pinning centers. On the contrary, the $REFeAs(O,F)$ family...
Iron-based superconductors have attracted a great deal of interests in both fundamental physics and potential applications. We have grown iron-chalcogenide FeSe0.5Te0.5 (FST) superconducting films on various single crystal substrates and metal substrates in coated conductors by pulsed laser deposition.[1] The FST films on CeO2 buffer layer exhibit...
Interfilamentary bridging in Bi2212 conductors influences the magnetization of magnets built using these conductors. Previous work has shown that the magnetization depends linearly on sample length and twist pitch, and a length-independent parameter describing the connectivity between superconducting filaments was introduced. However, this parameter has not yet been correlated to the bridged...
