In 2008, Chen’s group reported superconductivity above 40 Kelvin (-233 degrees Celsius) in an iron pnictide in Nature, suggesting iron-based superconductors form a second family of high ...

And in this paper, the scientists claim, they’ve shown for the first time that they can induce and observe these hot spots in a 3D sample of an iron pnictide superconductor. This comes after ...
