Welcome to the Microspectroscopy Group
The Microspectroscopy Group has a long experience in synchrotron based hyperspectral imaging for a wide variety of materials and involving many different scientific disciplines. In particular we study the nanostructures of novel organic materials and the magnetic properties of thin films and multilayers employing a combination of X-ray microscopy and spectroscopy. We operate two beamlines at the SLS, PolLux and NanoXAS. At these beamlines we perform our research and provide support for external users.
Recent Scientific Highlights and News:
Ferrimagnetic Skyrmions: fast and straight
Scientists have demonstrated, through magnetic X-ray microscopy, that magnetic skyrmions stabilized in ferrimagnetic heterostructures can be displaced by electrical currents at high velocities, and exhibit low deflection angles, proving that ferrimagnetic skyrmions are good candidates for fast skyrmionic devices.
Light amplification accelerates chemical reactions in aerosols
Aerosols in the atmosphere react to incident sunlight. This light is amplified in the interior of the aerosol droplets and particles, accelerating reactions. ETH and PSI researchers have now been able to demonstrate and quantify this effect and recommend factoring it into future climate models.
Into the fourth dimension: time-resolved soft X-ray laminography
Combining time-resolved soft X-ray STXM imaging with magnetic laminography, researchers were able to investigate magnetization dynamics in a ferromagnetic microstructure resolved in all three spatial dimensions and in time. Thanks to the possibility of freely selecting the frequency of the excitation applied to the magnetic element, this technique opens the possibility to investigate resonant magneto-dynamical processes, such as e.g. magnetic vortex core gyration and switching, and spinwave emission.
