Current Highlights and News
From light-years to nanometers: reconstruction of unknown oscillations in STXM
From light-years to nanometers: by repurposing an algorithm originally developed for the investigation of oscillatory dynamics in astronomical objects, scientists have been able to image non-locked dynamical processes at the nanosecond and nanometer scale.
Nucleation of synthetic antiferromagnetic skyrmions
Magnetic skyrmions stabilized in synthetic antiferromagnets hold promise as nanoscale information carriers in novel non-volatile magnetic memory designs. In this work, scientists in a worldwide collaborative effort have demonstrated the electrically-induced nucleation of magnetic skyrmions in synthetic antiferromagnets, which is a vital stepping stone towards the applicability of these magnetic textures in devices.
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.
