The geometries, stabilities, electronic, and magnetic properties of AunScm (n= 1–7, m=1,2) clusters have been systematically investigated by density functional theory. It is shown that the most stable structures of AunSc (n=1–7) clusters favor planar structure and Sc atom is prone to occupy the center site of Au atoms ring. For AunSc2 clusters, the 3d configurations become the lowest energy str...
