Abstract
To study the origin of the anomalous Hall effect, Fe100-x(SiO2)(x) granular films with a volume fraction of SiO2 (0 <= x <= 40.51) were fabricated using cosputtering. Hall and longitudinal resistivities were measured in the temperature range of 5-350 K with magnetic fields up to 5 T. As x increased from 0 to 40.51, the anomalous Hall resistivity and longitudinal resistivity increased by about four and three orders in magnitude, respectively. Analysis of the results revealed that the normalized anomalous Hall conductivity is a constant for all of the samples, which may suggest a scattering-independent anomalous Hall conductivity in Fe.
