Design and investigation of Sono-chemical synthesis of pure and Sn doped CoFe2O4 nanoparticles and their structural and magnetic properties

Research on the tuning of magnetic properties of the divalent ferrite materials is always having its own flavor due to their spectacular applications in the modern electronic and magnetic devices including magnetic data storage and magnetic tapes. In this present context, we have reported the sono-chemical synthesis of pure and Sn doped CoFe2O4 nanoparticles (NPs) and their structural, morphological and magnetic properties. Powder X-ray diffractometry (XRD) and scanning electronic microscopic (SEM) techniques have provide the clear details about the formation crystallographic structure and surface morphological features and obtained the XRD results showed that the stable cubic crystallographic structure and stable hard ferromagnetic state even at ultrasonic waves irradiated conditions. On the other hand, Sn doped CoFe2O4 has high coercivity (1621 Oe) compared than the pure CoFe2O4 and few technologically important doped CoFe2O4 important ions such as Gd3+, Tm3+, Eu2+ in CoFe2O4 NPs respectively and hence the Sn doped CoFe2O4 NPs is suggested the magnetic data storage applications.
