Effects of alloying on the electronic and magnetic properties of MnxCoy (x+y=n=2\ensuremath-5; x=0\ensuremath-n) and Mn2Co11 nanoalloy clusters are investigated using the density-functional theory. Unlike the bulk alloy, the Co-rich clusters are found to be ferromagnetic and the magnetic moment increases with Mn concentration and is larger than the moment of pure Con clusters of same size. For a particular sized cluster the magnetic moment increases by 2\ensuremathμB/Mn-substitution, which is found to be independent of the size and composition. All these results are in good agreement with recent Stern-Gerlach experiments [Phys. Rev. B 75, 014401 (2007) and Phys. Rev. Lett. 98, 113401 (2007)]. Likewise in bulk MnxCo_1\ensuremath-x alloy, the local Co moment decreases with increasing Mn concentration.
