Neutron scattering from correlated electron systems — •Bernhard Keimer — Max-Planck-Institut für Festkörperforschung

The unusual physical properties of materials with strong electronic correlations, such as high-temperature superconductivity, are currently at the forefront of condensed matter physics. The magnetic structure and dynamics elucidated by neutron scattering are incisive "fingerprints" of the microscopic mechanisms underlying this intriguing behavior. We will illustrate the power of neutron scattering with several examples, including cuprate and cobaltate superconductors and materials with orbital degeneracy. We will also illustrate novel perspectives opened up in this field by intense new neutron sources such as the FRM-II research reactor.
