S12: Recent Developments in High-Temperature Superconductivity

EMA 2014


Recently, significant progress has been made world-wide in both fabrication and fundamental understanding of high-temperature superconductors (HTS). For example, high-temperature superconductor (such as cuprates) wires and tapes have been commercially produced; advances continue to be made in fabrication and application of superconducting MgB2; and the iron arsenide family of superconductors has set off an intense search for new superconductors with even higher transition temperatures and lower anisotropies. However, challenges remain to increase the overall current carrying ability for applications and to correlate the interplay between structure, magnetism, and superconductivity in these superconductors on micro-, meso-, and nano-scales for fundamental understanding of the mechanism of superconductivity. This symposium will cover recent developments in the processing of  superconducting materials, improved flux-pinning via structural and defect optimization, and recent advances in the discovery of new superconducting materials. The development and status of applications, and the materials science drivers and issues for these applications will also be addressed.
