Abstract

Synchrotron experiments with uranium anti-ferromagnetic compounds have discovered large (>1000) enhancements of the magnetic scattering intensities at the K edges of nominally nonmagnetic anions, e.g., Ga and As. The width in energy, the position with respect to the white line, and the azimuthal and polarization dependencies permit one to associate the signal with transitions of E1 dipole symmetry from 1s to 4p states. In momentum space, the signal exhibits long-range order at the anti ferromagnetic wave vector. We discuss possible channels capable of generating the observed enhancements.
