Effect of Neodymium Dopping on Morphology, Phase Changes and Magnetic Properties of Ni0.7Zn0.3NdxFe2-xO4 Ferrite Nanoparticles Synthesized by Complexing Sol-Gel Method
: The purpose of this study was to evaluate phase changes and magnetic properties of neodymium doped Ni 0.7 Zn 0.3 Nd x Fe 2-x O 4 (x = 0, 0.01, 0.03, 0.05, 0.07, 0.10) nanoparticles synthesized by complexing sol-gel method. In this method, triethanolamine (TEA) acted as both a gelling agent and a chelating agent. Samples were characterized by X-ray diffraction (XRD) analysis, field emission scanning electron microscopy (FESEM), and energy dispersive X-ray spectroscopy (EDX). XRD patterns of all synthesized samples revealed the formation of a spinel ferrite phase. Magnetic evaluation of the specimens showed that the Nd 0.01 doped sample with a quasi-spherical morphology and particle size of about 60 nm has the highest saturation magnetization of 50 emu/g and coercive force of 103 Oe.
