Abstract

The effect of nickel doping on the structural and magneto-rheological properties of Fe₃O₄ based nanomagnetic fluids (NMFs) having the composition Ni_xFe_3-xO₄ (0 ≤ x ≤ 0.8) has been studied. The structural and compositional analysis confirmed the nanoscale regime (∼10 nm) of samples prepared by chemical co-precipitation method and structural analysis was performed by XRD pattern to ascertain the effect of Ni doping. From the UV–Visible spectroscopy studies, the energy band gap was found to be in the range 2.2–3.0 eV with increase in Ni concentration. The magnetic measurements reveal the lower values of coercivity and remanence. The magneto-rheological measurements confirm that in all samples shows a non-Newtonian shear thinning behavior and the increase of viscosity and dipolar interactions while increasing the magnetic field. Whereas in absence of field, higher grain boundaries enhance the interlayer friction and higher viscosity with Ni doping.
