Electrical and magnetic behavior of iron doped nickel titanate (Fe super(3+)/NiTiO sub(3)) magnetic nanoparticles

Iron doped nickel titanate (Fe super(3+)/NiTiO sub(3)) ferromagnetic nanoparticles with different concentrations of Fe (0.2, 0.4, and 0.6 mol) were synthesized using precipitation route with precursor source such as nickel nitrate and iron nitrate solutions. The prepared magnetic nanopowders were in...

Description
Summary:Iron doped nickel titanate (Fe super(3+)/NiTiO sub(3)) ferromagnetic nanoparticles with different concentrations of Fe (0.2, 0.4, and 0.6 mol) were synthesized using precipitation route with precursor source such as nickel nitrate and iron nitrate solutions. The prepared magnetic nanopowders were investigated through X-ray diffraction (XRD), Fourier transform infrared, scanning electron microscope, X-ray fluorescence, Brunauer-Emmett-Teller, vibrating sample magnetometer, and electrochemical impedance spectroscopy to explore the structural, ferromagnetic, and dielectric properties. The obtained XRD pattern shows formation of iron doped nickel titanate in orthorhombic structure. The crystallite size ranges from 57 to 21 nm and specific surface area ranges from 11 to 137 m super(2) g super(-1). The hysteresis loops of nanomagnetic materials show ferromagnetic behavior with higher magnitude of coercivity (H sub(c)) 867-462 Oe. The impedance analysis of ferromagnetic materials explores the ferro-dielectric behavior with enhanced properties of Fe super(3+)/NiTiO sub(3) nanoparticles at higher Fe content.
