Understanding the magnetic glue of superconductivity at ILL

New evidence suggests fluctuating magnetic stripes are the cause of mysterious hourglass magnetic spectrum of high temperature superconductors. 

Scientists at Oxford University and the Institut Laue-Langevin have used neutrons to probe the magnetic glue thought to produce high temperature superconductivity and have identified stripes of magnetic moments and charge as the cause of a strange hourglass-shaped magnetic spectrum. Their findings, reported in Nature, will aid the search for a model of high temperature superconductivity. A publication in Nature on 17th March
