Abstract

Nickel-zinc ferrite, Ni0.5Zn0.5Fe2O4 was prepared by a soft mechanochemical route from mixtures of Ni(OH)2, Zn(OH)2 and Fe(OH)3 powders in a planetary ball mill. The mechanochemical treatment provoked reaction leading to the formation of the Ni0.5Zn0.5Fe2O4 spinel phase what was monitored by XRD, TEM, SEM, IR and Raman spectroscopy. The spinel phase was first observed after 5h of milling and its formation was completed after 10 h. The synthesized Ni0.5Zn0.5Fe2O4 has a nanocrystalline structure with a crystallite size of about 16 nm. Four active modes are seen in the far-infrared reflectivity spectra. The Raman spectrum suggests an existence of mixed spinel structure in the obtained nano-powder samples..
