Abstract

In general, isotropically spherical structural products of magnetite are obtained when templates are not used. In this article, novel single-crystalline magnetite nanoplates were synthesized using a simple template-free solvothermal route. The magnetite nanoplates were characterized using techniques including X-ray powder diffraction (XRD), scanning electron microscope (SEM), transmission electron microscope (TEM), high resolution TEM and magnetometer. The results for the magnetic behavior exhibit that the magnetite nanoplates show a saturation magnetization of 84.7 emu/g, a remanence magnetization of 13.36 emu/g and a very high coercivity of 117.72 Oe at room temperature due to their peculiar morphology compared to that (0–110 Oe) of other morphological (polyhedral, cubic, solid and hollow spherical) magnetite.
