    "abstract": "We systematically investigate the structural, electronic and magnetic\nproperties of Mn$_n$ clusters ($n =$ 2$-$20) within the {\\it ab-initio}\npseudopotential plane wave method using generalized gradient approximation for\nthe exchange-correlation energy. A new kind of icosahedral structural growth\nhas been predicted in the intermediate size range. Calculated magnetic moments\nshow an excellent agreement with the Stern-Gerlach experiment. A transition\nfrom ferromagnetic to ferrimagnetic Mn$-$Mn coupling takes place at $n=$ 5 and\nthe ferrimagnetic states continue to be the ground states for the entire size\nrange. Possible presence of multiple isomers in the experimental beam has been\nargued. No signature of non-metal to metal transition is observed in this size\nrange and the coordination dependence of $d-$electron localization is\ndiscussed.",
