Abstract The paper describes creation of cobalt ferrous spinel ferrite nanoparticles and investigation of their phase composition, surface structure and magnetic properties. Cobalt ferrous spinel ferrite nanoparticles were synthesized in an aerated system of steel electrode contacting with aqueous cobalt chloride at different pH values of solution. According to X-Ray diffraction data, it was shown, that some impurity phases also formed during the synthesis process, notably, lepidocrocite and goethite on the steel surface and Green Rust I, cobalt hydroxide, heterohenite in the solution. The quantity of such phases depends on pH value of initial solution. The size of synthesized cobalt ferrous spinel ferrite nanoparticles was approximately 10 – 12 nm. Saturation magnetization of synthesized cobalt ferrous spinel ferrite nanoparticles is rather high. Synthesized magnetic cobalt ferrous spinel ferrite nanoparticles are promising for different medicalbiological applications.
