Abstract: K1.00185 : Unusual Structure and Magnetism in MnO Nanoclusters
Author:
We report an unusual structural and magnetic evolution in
stoichiometric MnO nanoclusters by an extensive and unbiased
search through the potential energy surface within density
functional theory. The $(MnO)_n$ nanoclusters adopt
two-dimensional structures in size ranges in which $Mn_n$
nanoclusters are three-dimensional and regardless of the size of
the nanocluster, the magnetic coupling is found to be
antiferromagnetic, and is strikingly different from Mn-based
molecular magnets. Both of these features are explained
through the inherent electronic structures of the nanoclusters.
