Resonant soft X-ray and extreme ultraviolet magnetic scattering in nanostructured magnetic materials: Fundamentals and directions

► We review the theory or resonant soft X-ray magnetic scattering. ► The interplay of resonant charge and magnetic scattering is emphasized. ► Resolving in-plane heterogeneity in thin films in transmission geometry is considered. ► Resolving in-depth heterogeneity in reflection geometry is considered. ► We review practical considerations for planning and interpreting measurements.
