Materials Researchers at Linköping University, Uppsala University¸ and Chalmers University of Technology, in collaboration with researchers at the Swiss Light Source (SLS), the Paul Scherrer Institute, investigated high-temperature superconductor, YBa2Cu3O7-x (YBCO), using advanced X-ray spectroscopy. YBCO is a cuprate ceramic material that becomes superconducting when it is cooled down below -183 °C. Since the resistance and the power losses are zero in the superconductors, they find many promising applications. Electromagnets in electric motors can be made smaller with

Caption: A comparison of XAS data from two different temperatures shows that cooling results in a redistribution of charges between the superconducting copper oxide planes and chains.
