CoFe2O4−Fe3O4 Magnetic Nanocomposites as Photocatalyst for the Degradation of Methyl Orange Dye
Figure 4
Temperature dependent magnetization curves measured at an applied field of 200 Oe (a) at low temperatures between 20 and 300 K under ZFC and FC conditions and (b) at high temperatures for as-prepared CoFe2O4–Fe2O3 magnetic nanoparticles. Inset: Plot of thermal derivative of magnetization with temperature.
