abstract = {Ternary FeCoNi metallic nanostructures have attracted significant attention due to their high saturation magnetization, unique mechanical properties, and large corrosion resistance. In this study, we report a controlled synthesis of ternary FeCoNi nanocrystals using solution-based epitaxial core–shell nanotechnology. The thickness and stoichiometry of the FeCoNi nanocrystals affect their magnetic characteristics, which can be controlled by a phase transformation-induced tetragonal distortion. Furthermore, surface oxidation of the stoichiometry-controlled FeCoNi nanostructures can drastically enhance their magnetic coercivity (up to 8, 881.6 Oe for AuCu–FeCo), and optimize the AuCu–FeCo0.8Ni0.2 performance corresponding to the saturated magnetization of 134.4 emu·g-1 and coercivity of 4, 036.7 Oe, which opens the possibility of developing rare-earth free high energy nanomagnets.}
