A series of FexSn100-x granular alloy films with different atomic fractions were fabricated by ion beam sputtering. The highest value ever observed for ferromagnetic metal/non-magnetic metal systems has been obtained. The extraordinary Hall effect was studied systemically by varying the atomic fractions and the thickness of the samples. With the power law between the saturated Hall resistivity and the resistivity the mechanism of the extraordinary Hall effect was also discussed.
