High critical current density doped pnictide superconductors

By Eileen De Guire / July 25, 2012

High critical current density doped ferropnictide superconductors. (a) Magneto-optical image of a rectangular slab of (Ba0.6K0.4)Fe2As2 bulk material after zero field cooling the sample to 10 K and applying 167 mT. (b) Current stream lines calculated for zero field cooled sample showing uniform current circulating though the bulk. (c) Magneto-optical image showing remnant trapped magnetic…
