Cation distribution of Ni_0.5Zn_0.5Fe₂O₄ nanoparticles

Abstract

A set of Ni_0.5Zn_0.5Fe₂O₄ samples were prepared by citrate precursor route to investigate the growth mechanism and its effect on cationic distribution. Following the information from DTA–TGA analysis, samples were annealed at 550 °C, 700 °C and 750 °C. Magnetization and Mössbauer studies suggest that initially the cationic distribution deviates from its normal preferences but it gets back to the normal preference at a temperature around 675 °C. It has been found that size onset for having the bulk cation configuration exclusively depends on the composition.
