Single phase, highly crystalline and uniform cobalt ferrite thin films were deposited on glass and silicon substrates in aqueous solutions at 80 °C through the liquid phase deposition (LPD) method. Regardless of the chemical composition, the CoxFe2-xO4 (0 < x < 1) thin films identified with a crystal structure as spinel-type are homogeneous, being constructed by spherical particles. The magnetic films present a hysteretic behavior at room temperature with saturation magnetization values close to the bulk material and coercivities depending on the cobalt content.
