Superparamagnetism was observed in antiferromagnetic MnO ultrafine-particles with the size range of 3.7∼5.4 nm. The decrease of Neel temperature in these finite systems was confirmed by measuring the temperature dependence of the magnetic susceptibility. The size dependence of a magnetic moment per atom and per particle was estimated by fitting the magnetic susceptibility to the Curie-Weiss law at higher and lower temperature than the Neel temperature, respectively. The former increased with… Expand
