Structural and magnetic properties of chemically synthesized [Sn.sub.1-x][Mn.sub.x][O.sub.2] nanocrystalline powders

The structural and magnetic properties of the [Sn.sub.1-x][Mn.sub.x][O.sub.2] nanocrystalline powders which was synthesized by a wet chemical method is discussed. The results indicate that Mn element acts as [Mn.sup.4} for x = 0.01 and as [Mn.sup.3} for x = 0.02 and 0.04 at room temperature, but as [Mn.sup.3} for all the samples of 5 K.
