Abstract: In this work we prepare nanocrystalline mixed ferrites by equilibrated low entropy routes with generic formula of MnxNi1-xFe2O4. Two series of samples have been prepared where x varies as 0.0, 0.1, 0.2, 0.3, 0.4 and 0.5 the samples have been prepared by chemical co-precipitation route. For the first calculated amount of salts of Mn, Fe and Ni were dissolved in deionized water and stirred for a few minutes. 0.1 M NH4OH solution was then slowly added drop-wise under vigorous stirring. The alkali addition was continued till the pH of the solution was 10 and was left undisturbed for 1hour for complete digestion.
