Iron/iron-oxide granular films were fabricated using reactive dc magnetron sputtering. Their structural, magnetic and transport properties were systematically studied. XPS and TEM confirmed the coexistence of Fe, FeO and Fe2O3. A metal-insulator transition was observed with the increasing of the oxygen component in the film. The temperature dependencies of longitudinal resistivity ρxx and anomalous Hall resistivity ρxy were discussed. We found the enhancement of ρxy and investigated the scaling law between anomalous Hall coefficient Rs and ρxx. In all the samples, Rs was found to be proportional to ρxx when ρxx is small, which indicated the skew scattering is dominant.
