为了获得磁性多层膜中的深度选择信息，我们提出了一种基于多个同位素传感器层的核共振散射的测量方案。它利用掠入射几何结构中光子波场强度的深度依赖性来增强来自多层膜的给定部分的信号。应用该技术研究了Fe/Fe氧化物/Fe三层膜的磁结构。我们能够完全确定在一个直接的方式嵌入在系统中的两个ADRF 57 e探针层的磁状态。所提出的技术可以潜在地扩展到各种掠入射X射线散射方法。
To obtain depth-selected information in magnetic multilayers, we propose a measurement scheme based on nuclear resonant scattering from multiple isotopic sensor layers. It takes advantage of the depth dependence of the photon wavefield intensity in grazing incidence geometry to enhance the signal from a given part of a multilayer. The technique is applied to study the magnetic structure of a Fe/Fe-oxide/Fe trilayer. We are able to fully determine in a direct manner the magnetic state of two ultrathin F57e probe layers embedded in the system. The proposed technique can potentially be extended to various grazing incidence x-ray scattering methods.
