Abstract
Nanostructured magnetite plates were synthesized by a simple solvothermal route where ethylenediamine was used as the solvent and reducing agent. The morphology and structure of the as-prepared platelets were characterized using X-ray diffraction, infrared spectroscopy and transmission electron microscopy. The results showed that the products are magnetite crystals with plate like morphology whose thickness is estimated to be 20 nm. Magnetic measurements at 300 K gave the saturation magnetization and the coercive field of nanostructured magnetite 87.4 emu/g and 178 Oe, respectively, which are higher than those of cubic nanoparticles, due to the higher shape anisotropy of magnetite nanoplatelets.
