Preparation of Fe Substituted ZnO Nanoparticles and Investigation of Their Magnetic Behaviors %K Diluted magnetic semiconductor %K Zinc oxide %K Sol-gel auto-combustion method %R 10.30492/ijcce.2018.30590 %X Nano-powders of diluted magnetic semiconductor Zn1-xFexO (0.0≤ x ≤0.1) were prepared via the sol-gel auto-combustion method. Crystal structure and phase identification carried out by X-Ray Diffraction (XRD) analysis. Mean crystallite size of the powders was estimated by Scherrer's formula. As M-H loops of the Fe substituted ZnO showed ferromagnetic behavior. The results of X-Ray Photoelectron Spectroscopy (XPS) showed that there is a mixture of Fe3+ and Fe2+ ions in all Fe substituted samples. Antiferromagnetic interaction between neighboring Fe3+-Fe2+ ions suppressed the ferromagnetic behavior of the samples at higher doping concentrations of Fe. %U https://ijcce.ac.ir/article_30590_d0c37d3a0ac46939272afe9bfbe5f805.pdf
