摘要：

Nickel ferrite (NiFe2O4) nanosheet has been synthesised by the polymer assisted co-precipitation method. The synthesised nanosheet was characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), high-resolution transmission electron microscopy (HRTEM), high-resolution scanning electron microscopy (HRSEM), thermal analysis and vibrating sample magnetometry (VSM). The results showed that the as synthesised NiFe2O4 has sheet like morphology with good crystalline nature. The nanosheet was formed through random aggregation of magnetic nanoparticles. Ferromagnetic property was exhibited by the nanosheet with saturation magnetization M-s = 35 emu/g, remanent M-r = 8.6 Oe and coercive force H-c = 192 emu/g. (C) 2010 Elsevier B.V.
