Optimizing a novel superconducting material

Optimizing a novel superconducting material: EU researchers initiated the Hipermag project to enhance the performance of MgB2 and thus increase commercial applicability and market penetration. Researchers successfully optimised the microstructure of precursor powders, demonstrating enhanced superconducting properties of carbon-doped nanosized precursors and wires (monofilamentary tapes).

They then developed powder processing techniques leading to development of multifilamentary conductors housed in metallic sheaths. The materials provided the enhanced mechanical stability lacking until now.

Researchers also improved current-carrying capabilities, employing a variety of microscopic and spectroscopic techniques to determine the preferred orientation of MgB2 crystallites. Finally, they evaluated the stability of the superconductors in magnetic fields, explaining novel experimental results with theoretical descriptions.
