We report on the observation of a dramatically increased extraordinary Hall Effect in Pt-based ferromagnetic alloy thin films with varying composition and thickness that were deposited using magnetron sputtering. Hall slope as high as 76.8 μΩ cm/T has been obtained at 110 K and 22.6 μΩ cm/T at 300 K. Excellent sensitivity, linearity, and a small temperature coefficient have been achieved in a particular composition, Fe35Pt65, for a film thickness of 10 nm. The optimized Fe–Pt thin films compare favorably with the commonly used semiconductor Hall sensors.
