The three-dimensional distribution of the Fe3Pt alloys prepared in this study with different degrees of chemical ordering is plotted in the figure (top). The size of ordered/disordered nanodomains and the lattice strain observed by high-resolution transmission electron microscopy is shown schematically in the lower left, and the magnetic moment modulation around the ordered/disordered interfaces is shown in the lower right.

Abstract: In solid-state matters, chemical ordering is often closely associated with their fantastic physical properties and specific chemical reaction mechanisms. Through the redistribution of atoms and chemical bonds, the modulation of chemical ordering can lead to effective lattice tuning and provide intrinsic lattice stress. However, the direct probing of the three-dimensional structure of chemically ordered/disordered interfaces remains a great challenge. Recently, the National Science Review published online the research results of Prof. Xianran Xing's group at the Institute of Solid State Chemistry, University of Science and Technology Beijing, which reveals the atomic distribution and lattice matching relationship of nano-scale ordered/disordered domains in Fe3Pt alloys with the help of the Pair Distribution Function (PDF) method. Through the lattice adjustment around the interfaces of nanodomains, the effective regulation of the magnetic properties and negative thermal expansion of lattice was obtained.

The present experimental and theoretical results from the research team provide convincing structural insights into the identification of the local structure of nanodomains in solids and the lattice matching around the interfaces, providing a structural basis for understanding chemical ordering at the atomic scale and developing new lattice design strategies.
