Direct observation of electronic excitations in copper oxide superconductors using the synchrotron radiation


  The characteristic electronic excitations of the copper oxide superconductor have been observed by the resonant inelastic x-ray scattering (RIXS) method using synchrotron radiation in SPring-8 facility. This study was cooperative work with JAERI. The results were published in Phys. Rev. Lett. on May 12 and May 26, as well as in Nikkan-Kogyo newspaper on August 11, 2005.One of the papers was selected in "Virtual Journal of Applications of Superconductivity".
