An organic precursor was obtained from cobalt nitrate and iron nitrate with different diols (etilendiol, 1,2-propanediol and 1,3-propanediol). The precursor was observed through thermal analysis and FT-IR spectrometry, techniques aimed at tracking the formation of carboxylate type complex combinations and establishing the optimal synthesis temperature. The formation of magnetic crystalline phases is observed through advanced heat treatments.
► All samples obtained have a hard magnetic behavior due to high anisotropy of CoFe2O4.
► The shape of magnetization curves are strongly influenced by temperature.
► Nature of crystalline phases depends on the nature of the diol used.
► By TEM we observed the presence of CoFe2O4 spherical nanoparticles of 20 nm in size.
► Nanocrystalites can be applied in cancer therapy in treating breast cancer tumors.
