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.
