Researchers find way to form diodes from superconductors

A group of researchers from Pisa, Jyväskylä, San Sebastian and MIT have demonstrated how a heterostructure consisting of superconductors and magnets can be used to create unidirectional current like that found in semiconductor ...

How small can superconductors be?

For the first time, physicists have experimentally validated a 1959 conjecture that places limits on how small superconductors can be. Understanding superconductivity (or the lack thereof) on the nanoscale is expected to ...

Iron age of high-temperature superconductivity

An international collaboration including Russian physicists from Moscow, Chernogolovka and Yekaterinburg have studied one member of the recently discovered family of superconductors based on iron compounds and find this exotic ...

Iron-based superconductors exhibit s-wave symmetry

(Phys.org) -- Condensed-matter physicists the world over are in hot pursuit of a comprehensive understanding of high-temperature superconductivity, not just for its technological benefits but for the clues it holds to strongly ...
