Magnetic properties of ZnMnO nanopowders solvothermally grown at low temperature from zinc and manganese acetate

The authors demonstrate that nanometer size ZnMnO nanopowders, grown from zinc and manganese (II) acetates at low temperatures under microwave radiation, are free of Mn clusters and the inclusion of Mn oxides. These nanopowders show a strong paramagnetic phase with only a weak antiferromagnetic contribution due to Mn-Mn interactions. (c) 2006 American Institute of Physics.
