Magnetic X-ray scattering
The cross-sections for magnetic scattering of electromagnetic radiation were worked out many years ago but are in general about 1.0 E-6 of the familiar cross-sections for charge scattering. The brilliance of present and projected synchrotron sources now make this technique one of considerable promise. Analysis of the cross-sections and of some recent results is presented, emphasising aspects such as the excellent wavevector resolution possible with synchrotron experiments. An important discovery of resonant magnetic scattering was made by Gibbs et al. in holmium. This occurs when the incident photon energy is tuned to certain absorption edges for the magnetic elements. A consequence is an enormous (greater than 1.0 E5 in the case of actinides) enhancement of intensity, making the technique of particular importance in the study of f-element magnetism. The paper concludes with speculation on some future possibilities of magnetic X-ray scattering.
