Researchers studying a distant spiral galaxy have found that large-scale, ordered magnetic fields existed far earlier in ...

Astronomers have detected ordered magnetic fields in galaxies so young that conventional models struggle to explain how those ...

Silicon nanospheres amplify second-harmonic generation from monolayer semiconductors over 40-fold while retaining ...

Multiferroic metals are materials that exhibit both electric polarization and magnetic order in the same crystal—a state ...

Scientists have succeeded in changing the polarity of a special ferromagnet using a laser beam. In the future, this method could be used to create adaptable electronic circuits with light. (Nanowerk ...

Learn how some of Earth’s magnetic field flips last longer than others, weakening our defenses against cosmic radiation. For at least 4 billion years, an invisible force field has enveloped our planet ...

An experimental technique that started life in nuclear and particle physics is now being used to measure chemical reactions inside the human body and to help diagnose cancer and heart disease in ...

A flexible screen inspired, in part, by squid can store and display encrypted images like a computer—using magnetic fields rather than electronics. The research is reported in Advanced Materials by ...

The researchers used a laser pulse (blue) to change the polarity of a ferromagnetic state in a special material consisting of twisted atomic layers (red). Researchers at the University of Basel and ...
