Among the magnetic materials employed in the field of information storage and electronic devices, chemically ordered binary alloys are of significant interest for the peculiar atomic arrangement in the lattice, which induces in the material a high magnetocrystalline anisotropy. Among the characterization techniques, X-ray absorption spectroscopy is an effective tool to probe the chemical environment around an absorber element and get information on the average structural features of the materials. In this contribution, the chemical order within different magnetic alloys (films and nanoparticles), has been investigated by XAS to understand the influence of specific process conditions on disordered-ordered transformation.
