Studies of magnetic order with synchrotron radiation: where do we go from here?

Abstract A short review of the available synchrotron light-based techniques for the study of magnetic materials is presented. Special emphasis is given to resonant scattering, where theoretical problems emerging from recent experiments at the K-edge of transition metal compounds are discussed. The magnetic and orbital order related scattering in V 2 O 3 is discussed in relationship to the problem of the electronic and magnetic structure of the antiferromagnetic phase, and K-edge magnetic scattering in 3d transition-metal compounds is briefly discussed in terms of a band-theory description.
