description | In present work, nickel ferrite magnetic nanoparticles were synthesized by simple precipitation method
using different surfactants and the effect of surfactants on its structural and magnetic properties have
been studied. Average crystallite size calculated from Scherrer formula is in the range of 20-51 nm.
Fourier transform infrared spectra confirmed the tetrahedral and octahedral vibrational bands at 400
and 650 cm-1, respectively. The UV-visible absorbance spectra confirmed that the direct bandgap of
nickel ferrite between 3.48 and 3 eV for different surfactants. Transmission electron microscope analysis
validated the establishment of single-phase nickel ferrite nanoparticles in the range of ~19-51 nm.
Saturation magnetization varies with surfactants between 28.6 and 50.3 emu/g, 76 to 95 Oe and 2.19
to 6.07 emu/g, respectively. The superparamagnetic nature of the samples is supported by the low
coercivity (< 100 Oe). |
