Abstract Co0.2Zn0.2Mn0.6Fe2O4 nanoparticles were prepared through the pyrolysis of polyacrylate salt precursors prepared via in situ polymerization of the metal salts and acrylate acid. The pyrolysis behavior of the polymeric precursors was studied by use of thermal analysis. The structural characteristics of the as-calcined products was analyzed by powder X-ray diffraction (XRD), transmission electron microscope (TEM) and electron diffraction (ED) pattern. The results revealed that the spinel ferrites had nanosized morphology and good crystallinity. Magnetic properties of the samples at room temperature were measured using a vibrating sample magnetometer (VSM), showing that the sample exhibited characteristics of weak ferromagnetism.
