摘要：

We have observed a very large extraordinary Hall effect (EHE) in a series of Fe-Pt thin films with various Fe contents. The origin of this remarkable EHE is the large spin-orbit interaction in the Fe-Pt alloys. At certain Fe content, the Hall resistivity can be saturated with a magnetic field less than 2 kG. The large EHE persists to room temperature with little change in magnitude. The EHE, which to our knowledge is the largest among magnetic transition metals, may find potential applications in magnetic sensors and nonvolatile magnetic random access memories. We will present structural analysis of the Fe-Pt films. (C) 1996 American Institute of Physics.
