A set of Ni0.5Zn0.5Fe2O4 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 0C, 700 0C and 750 0C. 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 0C. It has been found that size onset for having the bulk cation configuration exclusively depends on the composition.
