ABSTRACT
Nuclear resonant scattering of synchrotron radiation provides a powerful tool to study magnetic ordering in low-dimensional systems. The isotopic specificity of the method supports the use of probe layers to selectively address specific sites in the sample, in particular interfaces between materials with different magnetic properties such as hard/soft magnetic, FM/AFM, magnetic/ superconducting layers. Future applications will focus on timedependent phenomena as they occur during magnetic switching processes. Such processes critically rely on the depth dependence of the magnetic structure as it changes as function of time. With micro-and nanofocused beams the spatial resolution can be further increased, for example, by selecting individual magnetic layers in a cross-sectional transmission/reflection geometry. A very exciting perspective is the application of the method at future XFEL sources where it could help to understand the spatiotemporal evolution of ultrafast magnetic processes.
