Crystallographic and Magnetic Properties of M /NiZnFe2O4 Nano crystalline doping with some ions Preparing by Sol-gel Process

Abstract

Abstract

The citrate sol-gel process used for preparation of modified M/Ni Zn Fe2O4 (M = Al, Ce, Sm, and Zr) nanostructures and calcined at 800oC for 3h, in the air. The sol-gel process was used because of its potential for making fine, high purity and homogeneous powders. Sol-gel is a facial chemical method that has the possibility of preparing a reproducible material in nanoscale and the advantage of the calcination of reducing the total processing time and the calcination temperature. At this study it was added some cations through Ni0.5Zn0.5Fe2O4 such as Al2O3, Ce2O3, Sm2O3, Zr2O4 as the formula AlxNi0.5-xZn0.5Fe2O4 , where (x = 0.0, 0.1, 0.2, 0.3), CexNi0.5Zn0.5-x Fe2O4 , where (x = 0, 0.1,0.2,0.3), SmxNi0.5Zn0.5- xFe2O4 , where (x = 0, 0.2, 0.4, 0.5) and Sm0.4-XZrXNi0.5Zn0.1Fe2O4 ,where (x= 0.2,0.3), to study their effective structural, phase purity and magnetic properties. Prepared nano-sized pure and doped Ni0.5Zn0.5Fe2O4 were characterized by X-ray diffraction to investigate the crystalline phase and morphological characterization analyses, High-resolution transmission electron microscopy and scanning electron microscopy to confirm the formation of Ni-Zn ferrite nanoparticle and estimate the particle sizes, Fourier transforms infrared spectroscopy ensures the characteristic absorption bands of ferrites, investigate and confirmed the formation of spinel structure and Vibrating sample magnetometer to investigate the magnetic induction of the as- prepared sample.
