Neutron scattering experiment resolves a contentious superconducting issue

2014-08-04 – News from the Physics Department

Scientists around the globe are trying to understand the phenomenon of loss-free electric power transmission by high-temperature superconductors. Materials that exhibit this effect at room temperature would bear huge technical potential. Recently symmetry changes in the electronic phases of high-temperature superconductors near their transition temperature had been attributed to doping effects. But an international team of scientists has now discovered that solely spin dynamics of the electrons are responsible for these spontaneous changes.
