Demonstration of an iron-pnictide bulk superconducting magnet capable of trapping over 1 T
J. D. Weiss, A. Yamamoto, A. A. Polyanskii +3
A trapped field of over 1 T at 5 K and 0.5 T at 20 K has been measured between a stack of magnetized cylinders of bulk polycrystalline Ba0.6K0.4Fe2As2 superconductors 10 mm in diam…
Study of grain boundary transparency in (Yb1-xCax)Ba2Cu3O bi-crystal thin films over a wide temperature, field and field orientation range
Pei Li, Dmytro Abraimov, Anatolii Polyanskii +2
The residual low angle grain boundary (GB) network is still the most important current-limiting mechanism operating in bi-axially textured rare earth barium copper oxide (REBCO) co…
Mechanochemical synthesis of pnictide compounds and superconducting Ba0.6K0.4Fe2As2 bulks with high critical current density
J. D. Weiss, J. Jiang, A. A. Polyanskii +1
BaFe2As2 (Ba-122) and (Ba0.6K0.4)Fe2As2 (K-doped Ba-122) powders were successfully synthesized from the elements using a reaction method, which incorporates a mechanochemical react…
High intergrain critical current density in fine-grain (Ba0.6K0.4)Fe2As2 wires and bulks
J. D. Weiss, C. Tarantini, J. Jiang +4
The K- and Co-doped BaFe2As2 (Ba-122) superconducting compounds are potentially useful for applications because they have upper critical fields (Hc2) of well over 50 T, Hc2 anisotr…
Flux pinning characteristics in cylindrical ingot niobium used in superconducting radio frequency cavity fabrication
Asavari S. Dhavale, Pashupati Dhakal, Anatolii A. Polyanskii +1
We present the results of from DC magnetization and penetration depth measurements of cylindrical bulk large-grain (LG) and fine-grain (FG) niobium samples used for the fabrication…
Evidence for electromagnetic granularity in polycrystalline Sm1111 iron-pnictides with enhanced phase purity
A. Yamamoto, J. Jiang, F. Kametani +7
We prepared polycrystalline SmFeAsO1-xFx (Sm1111) bulk samples by sintering and hot isostatic pressing (HIP) in order to study the effects of phase purity and relative density on t…
