The use of anomalous X-ray scattering (AXS) at energies near the absorption edge of elements enables us to provide answers for various questions by making available accurate partial functions for individual pairs of constituents or the environmental structural functions around a specific element in multi-component materials. The AXS method works well for systems containing next neighbor elements in the periodic table, such as the distribution of cobalt in ferrite spinels or in amorphous ferrite glass. The present talk will demonstrate the usefulness and validity of the AXS method with some examples of aqueous solutions and thin films. The AXS method coupled with reverse Monte Carlo (RMC) simulation is also quite useful for providing the middle range (a few nm) ordering structure in both crystalline and non-crystalline states. This novel method provides a quantitative tool for describing imperfections in materials with complicated structure using polyhedral units. The usefulness of this method will also be presented by the results of corrosion products formed on the steel surface.
