Abstract

Using nickel and ferric nitrates and citric acid, NiFe₂O ₄ nanoparticles are prepared by a simple and cost-effective polyvinylpyrrolidone (PVP) assisted sol-gel auto-combustion method. The synthesised nanoparticles consist of single phase inverse spinel structure of NiFe₂O₄. The particles are in spherical shape with an average size of ∼8 nm. The vibrational properties show tetrahedral and octahedral sites of NiFe₂O₄ nanoparticles. The super-paramagnetism is observed with magnetic saturation (M_s) of 50.4 emug^-1.
