Scientists have new clues this week about one of the baffling electronic properties of the iron-based high-temperature superconductor barium iron nickel arsenide. Scientists have the first evidence, based on sophisticated neutron measurements, of a link between magnetic properties and the material’s tendency, at sufficiently low temperatures, to become a better conductor of electricity in some directions than in others.
