X-ray magnetic circular dichroism (XMCD) is a powerful technique that measures differences in X-ray absorption using circularly polarized light to reveal magnetic properties in materials. With much higher magnetic contrast than visible-light techniques, XMCD—especially when combined with advanced synchrotron sources and spectral analysis—enables precise, element-specific quantification of magnetic moments. As a key tool for investigating magnetic nanostructures and spin textures, XMCD has become essential for studying magnetism at the nanoscale and atomic scale. This review, with the participation of Group of Magnetic Nanomaterials, outlines the fundamental principles, experimental approaches, and wide-ranging applications of XMCD in modern magnetism research.»
