Cobalt nano-ferrite synthesized by molten salt process: structural, morphological and magnetic studies

Nanoparticles of CoFe2O4 were synthesized by molten salt process using non-standards reagents. The effects of experimental parameters on crystal structure, magnetic behavior, nanoparticles size and morphology will be studied. From the XRD patterns, pure spinel phase of cobalt nano-ferrite with space group Fd-3 m can be obtained from 900 degrees C, the FTIR confirms the XRD results by the two-absorption band characteristic of the crystal inverse spinel structure, TEM images show the evolution of nanoparticles size by temperature or annealing time, and magnetic measurements show a ferromagnetic behavior similar to magnetic behavior of cobalt ferrite elaborated by analytical grade reagents. Consequently, the CoFe2O4 synthesized by metallurgical grade reagent is multifunctional materials and has very competitive to other elaborated by commercial reagents for using in many nanotechnological applications as magnetic sensing, magnetic data storage and radiofrequency circuits.

Automated summary

The nanoparticles of CoFe2O4 synthesized by molten salt process using non-standard reagents exhibit excellent crystal structure and magnetic behavior, making them suitable for a wide range of nanotechnological applications.
