Abstract Hall effect measurements were carried out on rf-sputtered Fe3O4 and γ-Fe2O3 thin films in magnetic field up to 1.4 T applied perpendicular to the film plane. Their ordinary and extraordinary coefficients are determined from the experimental data. The calculated values of the Hall mobilities for these two films are 2.35 and 1.56cm2/V·s respectively, which are larger than 1 cm2/V·s, suggesting the occurrence of large polaron scattering. The extraordinary Hall effects were compared by using Berger side-jumping model. The negative magnetic resistivity is also observed for these two films.
