Iron-based Materials May Unlock Superconductivity’s Secrets

Caption: NIST researchers have found that new iron-based high-temperature superconductors subtly change their molecular shape as temperatures decrease. This graphic shows a superconductor transitioning from tetragonal (at top) to orthorhombic at about 220 Kelvin (-53 Celsius). Such physical changes appear to be a precursor to superconductivity, in which electric current can flow without resistance.
