| Abstract: | We report the preparation of metallic granular film Fe15.16Ag84. 84, grown on glass substrate and single crystals silicon substrate respectively, u sing magnetron sputtering method. The applied field H dependences of Hall effect and Hall coefficient RH in this specimen have been investigated. We observed the spin-dependent scattering anomalous phenomenon in the applied field H depend ence of Hall voltage UH, which suggests a corresponding relationship with the magnetoresistance. A proper explanation has been given based on spin-dependent s cattering effect or tunneling effect. |
