Abstract

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.
