Spin polarized dependent Hall effect in metallic granular film Fe15.16Ag84.84
Fe15.16Ag84.84金属颗粒膜自旋极化相关的霍尔效应研究

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.
