Abstract

In this research, the effect of rapid heating process on the magneto-optic conversion of the Co-doped Fe3O4 nanostructures prepared by the co-precipitation method is introduced. The variation of relative magnetization of these nanostructures were determined as a function of heating temperature in case these nanostructures are not irradiated with intensive light (laser) and then in case of irradiated with laser to determine the efficiency of magneto-optic conversion. Also, the relative magnetization of these nanostructures was determined as a function of the doping level with cobalt in the Fe3O4 nanostructures. Results showed that both light irradiation and doping level have reasonable effects on the magneto-optic conversion characteristic that may serve the practical applications of these ferromagnetic materials.
