论文摘要
铁磁材料中的自旋吸收过程取决于旋转方向相对于磁化。我们使用铁磁体吸收在侧面锥体内产生的纯自旋电流，我们证明并量化了自旋吸收INCO，COFE和NIFE的较大方向依赖性。这些实验允许确定旋转电导，这是自旋依赖性转运的难以捉摸的基本参数。我们表明，仅考虑LARMOR，横向反应性和旋转长度的模型中可以理解获得的值量，而是暗示了旋转混合电导实际上受thesharvin电导的限制。
The spin absorption process in a ferromagnetic material depends on the spin orientation relativelyto the magnetization. Using a ferromagnet to absorb the pure spin current created within a lateralspin-valve, we evidence and quantify a sizeable orientation dependence of the spin absorption inCo, CoFe and NiFe. These experiments allow determining the spin-mixing conductance, an elusivebut fundamental parameter of the spin-dependent transport. We show that the obtained valuescannot be understood within a model considering only the Larmor, transverse decoherence and spindiffusion lengths, and rather suggest that the spin-mixing conductance is actually limited by theSharvin conductance.
