Abstract:	We prepared NiZnCu ferrite powders with nominal composition Ni_0.4−xZn_0.6Cu_xFe₂O₄ (x=0-0.2) via chemical coprecipitation method with NaOH and Na₂CO₃ as coprecipitators. The structural and magnetic properties of these compounds were studied and compared. It is found that all the specimens exhibit single-phase structure after annealing. The saturation magnetization of specimens with NaOH as coprecipitator is lower than that with Na₂CO₃ as coprecipitator. It is also found that the growth of grains is hindered for specimens using Na₂CO₃ as coprecipitator.
