Controlling skyrmions for better electronics

Physicists at the University of Hamburg managed for the first time to individually write and delete single skyrmions, a knot-like magnetic entity. Such vortex-shaped magnetic structures exhibit unique properties which make ...

Improved X-ray microscopy makes fluctuations visible

X-ray microscopy requires radiation of extremely high quality. In order to obtain sharp images instrument and sample must stay absolutely immobile even at the nanometer scale during the recording. Researchers at the Technische ...

Competition is at the root of diversity in rainforests: study

Another attractive theory falls foul of the facts. A census of trees in rainforests on three continents has confirmed that competition plays a central role in structuring communities. This contradicts the so-called neutral ...

What is glass and how is it shaping our world?

From fiber optic cables to smartphones, glass is playing a major role in emerging technology. To learn more about how glass will shape future society, we spoke with Katelyn Kirchner, a doctoral candidate at Penn State, who ...

Magnetic vortices defy temperature fluctuations

Magnetic nanovortices in magnetite minerals are reliable witnesses of the earth's history, as revealed by the first high-resolution studies of these structures undertaken by scientists from Germany and the United Kingdom. ...

Observation of skyrmions in a ferromagnet with centrosymmetry

Researchers from the National Institute of Materials Science (NIMS) have used Lorentz electron microscopy to show that magnetic skyrmions are spontaneously formed as nanomagnetic clusters in a ferromagnetic manganese oxide ...
