Geometrically, there are an infinite number of alloy crystal structures, but only a few structures have actually been synthesized due to thermodynamics. In recent years, there have been many reports of the formation of metal nanoparticles with metastable phase by nano-size effects, but most of the metastable phases synthesized have well-known crystal structures, and the development of new crystal structures remains unexplored. In this presentation, We will report that we have succeeded in forming an unprecedented Z3-type Fe(Pd,In)₃ structure by a small amount of In, which is miscible with Pd but immiscible with Fe, into an FePd₃ alloy.
