Abstract

Ti_xCo_1+xFe_2-2xO₄ (0 ≦ x ≦ 0.5) ferrite films and its composite films with CoFe₂O₄ synthesized by a sol-gel method were investigated on crystallographic and magnetic properties. Magnetization decreased with the increase of Ti content while coercive force showed a maximum at x = 0.2 and comparatively high at x = 0.5. Composite films of Ti_0.5Co_1.5FeO₄ and CoFe₂O₄ showed larger H_c and smaller grains.
