提出了一种利用线偏振光源的X射线傅里叶变换全息术对磁畴进行成像的方法。我们的方法是基于全息掩模和样品的分离和参考波上引起的法拉第旋转。我们比较图像的垂直磁畴获得的线性或圆偏振的X射线和讨论这种方法的相关性，在自由电子激光器和高次谐波产生源的未来实验。
We present a method for imaging magnetic domains via x-ray Fourier transform holography at linearly polarized sources. Our approach is based on the separation of holographic mask and sample and on the Faraday rotation induced on the reference wave. We compare images of perpendicular magnetic domains obtained with either linearly or circularly polarized x-rays and discuss the relevance of this method to future experiments at free-electron laser and high-harmonic-generation sources.
