Abstract
The effects of manganese doping on the structural, mechanical, optical, and magnetic properties of zinc ferrite nanoparticles ( x = 0.00, 0.03, 0.06, 0.10) are reported. The variation in lattice parameters, average crystallite sizes, and the cation distribution of the mixed-spinel NPs were noticed. The spherical morphologies and particle sizes were observed using scanning electron microscopy (SEM), and the elemental composition was found using energy dispersive x-ray (EDX) spectroscopy. The FT-IR spectra showed significant absorption bands, and the values of Debye temperature (θ D) increased with the doping of Mn2+ content and an increase in the lattice vibrations. UV-visible diffuse reflectance spectroscopy (DRS) was used to find the optical energy bandgap values from 1.87 to 1.98 eV. The magnetic properties were evaluated using a vibrating sample magnetometer (VSM). Significant variations between the experimental and theoretical magnetic moments were observed, suggesting that the present system showed Yafet-Kittel type magnetic ordering.
