We have found that only Al atoms are present in the first coordination shell of both Sm and TM species. The structural disorder around Sm atoms is significantly higher then around TM. The interatomic distances between Al and Sm atoms are equal to the sum of their metallic radii within the experimental error, while Al–TM bonds are shortened by 10%. A slight decrease in TM coordination along with increase of TM content is observed. The evaluated coordination number of Sm is approximately 16 for all investigated systems and TM coordination ranges form 5 to 6.

Local atomic order in series of Al–(Y, Sm)–TM (TM = transition metal: Co, Ni) amorphous, melt-spun alloys was investigated by Sm 元-edge and TM K-edge X-ray absorption fine structure (XAFS) method. This method is attractive for a broad range of materials and experimental conditions. Integration of RDFs allows us to quantify the changes in the iron coordination and material density, and to observe the transition from body-centered to face-centered cubic arrangement of iron atoms. We illustrate this capability by extracting the radial distribution function (RDF) of atoms in ferritic and austenitic phases of bulk iron across the temperature-induced transition. Here we use artificial neural network approach to extract the information on the local structure and its in-situ changes directly from the X-ray absorption fine structure spectra. Many structural motifs and their transformations are difficult to detect and quantify in the process of work (operando conditions), due to their local nature, small changes, low dimensionality of the material, and/or extreme conditions. The knowledge of coordination environment around various atomic species in many functional materials provides a key for explaining their properties and working mechanisms.
