Scientists introduce magnetic data storage of the future

Single-molecule magnets (SMMs) have been attracting a lot of attention recently. This is because of the increased demand for faster, longer-lasting and lower-energy IT systems, and the need for higher data storage capacity.

Writing and deleting magnets with lasers

Scientists at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) together with colleagues from the Helmholtz-Zentrum Berlin (HZB) and the University of Virginia have found a way to write and delete magnets in an alloy using ...

Scientists uncover how to stop cyber intrusions

U.S. Army-funded researchers at the University of California in Los Angles have found a proverbial smoking gun signature of the long sought-after Majorana particle, and the find, they say, could block intruders on sensitive ...

One string to rule them all

Strain can be used to engineer unusual properties at the nanoscale. Researchers in Tobias Kippenberg's lab at EPFL have harnessed this effect to engineer an extremely low-loss nanostring. When plucked, the string vibrates ...
