Description
Recently we have combined a scanning transmission x-ray microscopy (STXM) setup with a novel microwave synchronization scheme for studying high frequency magnetization dynamics in the GHz regime [1] enabeling spatially resolved ferromagnetic resonance (FMR) studies on magnetic micro- and nanostructures. Compared to other spatially resolved FMR detection schemes [2] the STXM-FMR setup features element-selectivity as well as high temporal and spatial resolution down to 18 ps and 35 nm [1]. We will briefly present the STXM-FMR detection [1] and first results for coupled magnetic structures (Co stripe coupled to Py dot).
