我们提出了一种线偏振部分相干X射线源高分辨率磁成像的方法。通过傅里叶变换全息术实现了磁成像。为了实现椭圆X射线偏振，根据X射线磁性圆二色效应，设计了三种不同的滤光片。我们给出了磁性纳米结构的原理证明图像，并讨论了该方法在未来自由电子激光光源实验中的应用。
We present a method for high-resolution magnetic imaging at linearly polarized partially coherent x-ray sources. The magnetic imaging was realized via Fourier transform holography. In order to achieve elliptical x-ray polarization, three different filters were designed based on the x-ray magnetic circular dichroism effect. We present proof-of-principle images of magnetic nanostructures and discuss the application of the method for future experiments at free-electron laser sources.
