Journal of Magnetism and Magnetic Materials 226-230 (PART II) : 1382-1384. ScholarBank@NUS Repository.||Abstract:||Magnetic and Mössbauer measurements have shown that 1-2wt% of SiO 2 were solved in the CoFe2O4 structure after mechanical milling and subsequent heat treatment. Coercivity values up to 3.5 kOe were measured for CoFe2 O4/SiO2 powders. High coercivities were also achieved in SiO2 doped Co-ferrite thin films prepared by sputtering technique. The Co-ferrite thin film deposited on silicon wafer using a 5 wt%-SiO2/Co-ferrite target possessed a coercivity of 7.4 kOe, which is the highest value in Co-ferrite and spinel materials according to our knowledge. © 2001 Elsevier Science B.V.
