Attosecond boost for electron microscopy

Attosecond time resolution in a transmission electron microscope by combining it with a continuous-wave laser achieved

13-Nov-2020

Electron microscopes provide deep insight into the smallest details of matter and can reveal, for example, the atomic configuration of materials, the structure of proteins or the shape of virus particles. However, most materials in nature are not static and rather interact, move and reshape all ...

Taking magnetism for a spin

Exploring the mysteries of skyrmions

28-Jan-2019

Scientists at the U.S. Department of Energy's Ames Laboratory have discovered the relaxation dynamics of a zero-field state in skyrmions, a spinning magnetic phenomenon that has potential applications in data storage and spintronic devices. Skyrmions are nanoscale whirls or vortices of magnetic ...
