Abstract
Nickel ferrite (NiFe 2O 4) 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 NiFe 2O 4 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.
