Abstract

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 ρ_xx and anomalous Hall resistivity ρ_xy were discussed. We found the enhancement of ρ_xy and investigated the scaling law between anomalous Hall coefficient R_s and ρ_xx. In all the samples, R_s was found to be proportional to ρ_xx when ρ_xx is small, which indicated the skew scattering is dominant.
