Simple and effective preparation of cobalt ferrite nanoparticles by microwave-assisted solvothermal method

Abstract

Cobalt ferrite nanoparticles were successfully prepared by microwave-assisted solvothermal method utilizing microwave pressurized reactor. Final product was obtained in 30 minutes in a high yield and at relatively low temperature. As-prepared ferrite is consisted of polyhedral particles with an average particle size of 10 nm, exhibit high purity and can be classified as soft ferromagnetic material which magnetic properties are sufficient in comparison with similar materials in application.
