Studying nanomagnets by XMCD PEEM — •Florian Kronast — Helmholtz-Zentrum Berlin für Materialien und Energie

At the nanoscale magnetic materials exhibit novel physical, chemical, electrical, and optical properties that are relevant to a wide variety of applications. Investigations of static and dynamic properties of such low-dimensional structures require spectro-microscopy tools capable of appropriate lateral and temporal resolution, such as the synchrotron based photoemission electron microscope (PEEM) operated at Hemholtz-Zentrum Berlin. The combination of element-specific magnetic contrast with temporal and lateral resolution offers a unique toolbox for magnetic nanoscale science. This paper will present a review on recent activities ranging from the investigation of magnetic nanostructures found in meteorites to the microscopic mechanism behind all-optical magnetic switching and its scalability to the nanometer level.
