This paper investigates the magnetic properties of Co-ferrite (CoFe2O4) thin films deposited by sol-gel method with spin coating, especially coercivity related to the nanostructure of the films varying film thickness and annealing temperature. High coersivity of around 6 kOe and high magnetization of over 250 emu/cm3 were obtained in these thin films. The microstructure of the films with high coercivity were columnar that appeared 875K which showed magnetic anisotropy.
