基于波带片技术的高分辨率透射X射线显微镜（TXM）与提供巨大磁对比度的X射线磁圆二色性（X-MCD）相结合是一种对磁畴结构进行成像的新技术。它本质上是元素特定的，并且包含有关吸收物质的局部自旋和轨道矩的信息，这些信息可以通过应用磁光和规则获得。根据波带片的质量，可以实现低至 30 nm 的横向空间分辨率。我们报告了非晶态和多层 Gd-Fe 系统中 Fe L-3、L-2 边缘的初步结果。通过 BESSY 的 TXM 设置，我适应了在不同磁场中记录磁图像，研究了完整磁滞回线内磁域的演化以及磁后效应。
The combination of the high-resolution transmission x-ray microscope (TXM) based on the zone plate technique with the x-ray magnetic circular dichroism (X-MCD) providing a huge magnetic contrast is a new technique to image magnetic domain structures. It is inherently element specific and contains information on the local spin and orbital moments of the absorbing species that can be obtained by applying magneto-optical sum rules. A lateral spatial resolution depending on the quality of the zone plates down to 30 nm can be achieved. We report on first results at the Fe L-3,L-2 edges of Fe both in amorphous and in multilayered Gd-Fe systems. With a TXM set-up at BESSY I adapted to record magnetic images in varying magnetic fields the evolution of magnetic domains within a complete hysteresis loop and magnetic aftereffects have been studied.
