Two spin liquids square off in an iron-based superconductor

Despite a quarter-century of research since the discovery of the first high-temperature superconductors, scientists still don't have a clear picture of how these materials are able to conduct electricity with no energy loss. ...

Linking superconductivity and structure

Superconductivity is a rare physical state in which matter is able to conduct electricity—maintain a flow of electrons—without any resistance. It can only be found in certain materials, and even then it can only be achieved ...

Visualizing how radiation bombardment boosts superconductivity

Sometimes a little damage can do a lot of good—at least in the case of iron-based high-temperature superconductors. Bombarding these materials with high-energy heavy ions introduces nanometer-scale damage tracks that can ...

Study proposes new way to measure superconducting fluctuations

A study published last month by researchers at the U.S. Department of Energy's Argonne National Laboratory provides theoretical evidence for a new effect that may lead to a way of measuring the exact temperature at which ...
