Resonant x-ray magnetic scattering at nonmagnetic ions

An explanation is given for the resonant x-ray magnetic scattering effects at the K edge of nonmagnetic ions observed by Mannix et al. ͓Phys. Rev. Lett. 86, 4128 ͑2001͔͒. By using a description that goes beyond the usual fast-collision approximation, we can relate the scattering amplitude to the orbital moments on sites neighboring the nonmagnetic ion where the absorption takes place. The finite scattering amplitude is directly related to the resonant process, which explains the strong enhancement over the nonresonant intensity.
