我们描述了一种基于自旋相关的电子在Fe（100）表面的镜面反射的新型自旋偏振计的概念、设计和性能。Fe表面在Ag（100）上被制备成一层致密的薄膜。通过将电子的能量调谐到Fe能带结构中的临界点，实现了与大散射效率相结合的大自旋不对称性。我们描述了一种基于自旋相关的电子在Fe（100）表面的镜面反射的新型自旋偏振计的概念、设计和性能。Fe表面在Ag（100）上被制备成一层致密的薄膜。通过将电子的能量调谐到Fe能带结构中的临界点，实现了与大散射效率相结合的大自旋不对称性。旋光仪得出的最佳Fe（100）表面的品质因数高达10−2。
We describe concept, design, and performance of a novel spin polarimeter based on spin-dependent specular reflection of electrons from a Fe(100) surface. The Fe surface is prepared as an ultrathin film on Ag(100). By tuning the energy of the electrons to a critical point in the Fe band structure, a large spin asymmetry combined with a large scattering efficiency is achieved. The polarimeter yields a figure of merit up to 10−2 for the best Fe(100) surfaces.We describe concept, design, and performance of a novel spin polarimeter based on spin-dependent specular reflection of electrons from a Fe(100) surface.
