Scientists control superconductivity using spin currents

A group of researchers from institutions in Korea and the United States has determined how to employ a type of electron microscopy to cause regions within an iron-based superconductor to flip between superconducting and non-superconducting ...

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 ...

Unparticles may provide a new path to superconductivity

(—Physicists have proposed that a hypothetical form of matter called "unparticles" may play a key role in mediating superconductivity—the ability of certain materials to conduct electricity with zero resistance.
