Researchers from the Max Born Institute in Berlin have successfully performed X-ray Magnetic Circular Dichroism (XMCD) experiments in a laser laboratory for the first time.

Unlocking the secrets of magnetic materials requires the right illumination. Magnetic x-ray circular dichroism makes it possible to decode magnetic order in nanostructures and to assign it to different layers or chemical elements. Researchers at the Max Born Institute in Berlin have succeeded in implementing this unique measurement technique in the soft-x-ray range in a laser laboratory. With this development, many technologically relevant questions can now be investigated outside of scientific large-scale facilities for the first time.

Magnetic nanostructures have long been part of our everyday life, e.g., in the form of fast and compact data storage devices or highly sensitive sensors. A major contribution to the understanding of many of the relevant magnetic effects and functionalities is made by a special measurement method: X-ray Magnetic Circular Dichroism (XMCD).
