Investigating the Dielectric, Magnetic, and Optical Properties of Neodymium Doped Nickel Zinc Ferrites (Ni 0.4 Zn 0.6 Nd x Fe 2− x O 4 )

with varying concentrations of neodymium (x = 0,0.025,0.05,0.075, 0.1) by sol gel method. The effect of neodymium doping on the structural parameters, magnetic properties, dielectric behavior, AC conductivity, and optical properties has been investigated in detail. Formation of a single phase in all prepared compositions except at x = 0.1 was confirmed by the XRD technique. The EDX analysis has confirmed the compositional uniformity and high purity. The VSM analysis has revealed ferrimagnetic behavior of the doped ferrites. The composition with neodymium content, x = 0.05, is reported to have the lowest coercivity, minimum dielectric loss and reasonably good dielectric constant; therefore can be considered as a potential candidate for high frequency applications. The UV-DRS measurements have revealed a decrease in bandgap thereby indicating possible photocatalytic applications.
