Maghemite (?-Fe2O3) nanoparticle has been successfully synthesized by alginate template and by using reactant FeCl3, FeSO4, and NaOH at constant molar ratio 6:3:8 with variation of alginate template and reactant concentration. Maghemite nanoparticle was characterized by using FTIR, XRD, TEM, and VSM. Characterization results show that variation in alginate template concentration and reactant FeCl3, FeSO4, and NaOH in constant molar ratio give influence to grain size and amorphicity of maghemite nanoparticle which give influence to magnetic properties of maghemite nanoparticle.
