We are developing new measurement capability to study some of the fastest spin dynamics in magnetic thin films, devices and nanostructures by use of an ultra-fast, high-harmonic-generation, coherent light source.  This system generates ~ 10 fs pulses of coherent extreme ultraviolet light (10-100 eV) that is used to probe far-from-equilibrium magnetic structure with element specificity. For most of the materials of relevance to magnetic technologies (such 3-d transition metals), these elements have M-edges within the 10-100 eV range, which allows the dynamics of each element to be separated. In addition, the high coherence of the light source allows us to exploit lensless imaging modalities that include holography and coherent diffractive imaging (CDI). Such modalities have the potential to image magnetic processes at the nanosecond to femtosecond time scales with 15-30 nanometer resolution. We are also applying this system to understand both far-from-equilibrium processes, and the conversion of energy and angular momentum to and from the electronic system, spin system and crystal lattice. To support this effort, we have the full thin film and nanofabrication capabilities required to generate samples and test structures to be investigated. In addition, within our project is a suite of characterization and support instrumentation that includes broadband ferromagnetic resonance (FMR) spectroscopy, Brillouin light scattering (BLS) spectroscopy, electron microscopy, atomic/magnetic force microscopy, and a novel heterodyne magneto-optical microwave microscopy (H-MOMM). This effort is focused to support several developing technologies such as nonvolatile memory by the microelectronics industry.
