Abstract

Using nickel zinc and ferric nitrates and glycine in a fuelrich composition Ni1−x Zn x Fe2O4 nanoparticles were prepared by a simple lowtemperature autocombustion method without further sintering at high temperatures The autocombusted powders obtained were characterized by Xray diffraction XRD Raman spectroscopy scanning electron microscopy energydispersive Xray EDAX analysis and vibrating scanning magnetometer measurements XRD confirms the formation of pure nanocrystalline spinel phases with an average diameter of about 55 nm Raman spectra show tetrahedral and octahedral sites in the structure of Ni1−x Zn x Fe2O4 and also imply the doping of Zn2+ and displacement of Fe3+ ions from the tetrahedral site EDAX showed that the samples were close to the nominal compositions The magnetic measurement shows that the saturation magnetization and remanence magnetization decreases with the increase in the zinc content
