Magnetic and Structural Investigation of Ni1-xZnxFe2O4 (x = 0, 0.6, 0.8, 1) Spinel Ferrite Synthesized by Sol-Gel Auto Combustion Method

Abstract

Ferrite samples of Ni1-xZnxFe2O4 (x = 0, 0.6, 0.8, 1) nanoparticles were synthesized by the sol-gel auto-combustion technique. The goal of this research module is to evaluate the structural and magnetic properties of Ni2+ and Zn2+doped ferrite. X-ray diffraction (XRD) and vibrating sample magnetometer (VSM) analysis were carried out in order to characterize the structural and magnetic properties of synthesizing nanoparticles. The XRD results confirmed the formation of a single phase of spinel ferrite particles for an entire series of the material. The particle size was found to be nanometer range around 20 - 30 nm. The lattice parameter also calculated using XRD interpretation and the cation distribution also discuss briefly in the present research module. It was found that with an increase in substitution contents of Zn2+ ions the magnetization goes on decreases this may be due to the occupation of Zn2+ cations at both the site of octahedral and tetrahedral which causes to vary the magnetic interaction.
