As nanoelectronics encounters fundamental barriers, the spin of an electron, in addition to its charge, is being utilized to carry information in electronic devices. This calls for new characterization and detection methods of spin modes in complex magnetic structures. Present techniques measure either material properties on the nanometer length scale or on the picosecond time scale, however, both are needed simultaneously to obtain a complete picture in order to advance future technological developments.
