Poly(acrylic acid) (PAA) coated-Fe3O4 superparamagnetic nano-composites were synthesized through a solvothermal technique by using cheap and environmental friendly iron salts and PAA. Each nano-composite was composed of many small primary nanocrystals. The as-synthesized products were characterized by X-ray diffraction (XRD)
