我们报道了极化氦 - 3气体自旋过滤器技术在带有自旋分析的自旋极化漫中子反射率测量中的应用。自旋过滤器与一维位置敏感探测器一起，能够在利用自旋敏感性的同时对倒易空间中的区域进行同步研究。来自铁/铬超晶格的漫中子散射的一个例子展示了该方法的潜力。此外，我们通过利用超矩阵形式理论，朝着解释磁性多层膜的漫散射迈出了第一步。（C）2001美国物理学会
We report on the application of the polarized He-3 gas spin filter technique for the measurement of spin-polarized diffuse neutron reflectivity with spin analysis. The spin filter together with a one-dimensional position-sensitive detector enables the simultaneous investigation of sections in reciprocal space while exploiting spin sensitivity. An example of diffuse neutron scattering from a Fe/Cr superlattice demonstrates the potential of the method. In addition we present a first step towards the interpretation of diffuse scattering from magnetic multilayers by exploiting the supermatrix formalism. (C) 2001 American Institute of Physics.
