Abstract
The Bi3+ ions doped spinel Nickel ferrite NiBixFe2-xO4 (NBF) where, x = 0, 0.025, 0.050, 0.075, 0.1, 0.125, 0.150 was synthesized by sol–gel auto combustion method. The properties of prepared NBF were studied by using X-ray diffraction, UV–Vis spectroscope, Vibrating Sample Magnetometer, Fourier Transform Infrared Spectroscopy, Atomic Force Microscope, Scanning electron microscope, etc. X-ray diffraction showed that increasing the concentration of Bi3+ ions led to a decrease in crystallite size from 34 to 11 nm and lattice parameters ranging from 8.339 to 8.315 Å, confirming the formation of single-phase cubic spinel structure NBF also the crystallite size calculated by using Williamson Hall plot, is 15 to 36 nm. The energy band gap studied using UV–Vis spectroscopy decreases from 1.510 to 1.418 eV. The dielectrics and AC conductivity of NBF were studied by LCR-Q meter by varying frequency.
