| A novel one step room temperature synthesis of nanocrystalline Mn3O4 hausmannite was carried out from a simple dissolution of manganese(II) acetate, in a mixture of N,N'-dimethylformamide (DMF) and water. Homogeneous nanocrystals like rods were obtained, with an average width and length of 6.6 ± 1.2 nm and 17.4 ± 4.1 nm respectively, and a preferential growth along the <001> direction. Magnetization measurements on a powdered sample showed a ferrimagnetic behavior at low temperature. The blocking temperature (TB) was observed at 37K and the Curie temperature (TC) at 40K. |
