Abstract

NiFe ₂O ⁴ nanoparticles are prepared by a simple and cost-effective method using via polyvinyl alcohol assisted sol-gel auto-combustion method. The X-ray diffraction result indicated that the synthesized nanoparticles have only the inverse spinel structure without the presence of any other phase impurities. HR-SEM and TEM images showed that the particles are spherical shape with particle size in the range ∼11 nm. The magnetic property of these nanoparticles is studied for the enlightening ferromagnetic behaviour at room temperature. The value of the magnetic saturation (M _s) is 44.3 emug-1, remanent magnetization (Mr) is 19.8 emug-1 and coercive force (Hc) is 672.02 Oe.
