  • 采用磁控溅射法分别在玻璃和单晶硅衬底上同时制备了Fe15.16Ag84.84金属颗粒膜样品,并对样品的霍尔效应和霍尔系数RH随外加磁场H的变化关系进行了 实验研究. 观察到霍尔电压UH与外加磁场H的关系曲线呈现出自旋极化相关的反常现象,并 与其磁电阻效应具有对应关系.基于自旋相关的散射理论对此作出了合理的解释.

     

    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.
