We observed anomalous field dependence of Hall resistivity on Fe/Cr samples exhibiting large magnetoresistance. Hall resistivity of Fe(12.5)/Cr(12.5) shows a maximum near 2.3 T, above which it decreases 25%. The result was explained by the field-dependent decrease of the side-jump and skew scatterings in these samples. We also observed a clear correlation between the layer periodicity dependence of negative magnetoresistance and anomalous Hall resistivity in lower fields.
