California supervolcano is cooling off but may still cause quakes

Since the 1980s, researchers have observed significant periods of unrest in a region of California's Eastern Sierra Nevada mountains characterized by swarms of earthquakes as well as the ground inflating and rising by almost ...

Small-scale magnetism leads to large-scale solar atmosphere

Thanks to close-up images of the sun obtained during Solar Orbiter's perihelion passage of October 2022, solar physicists have seen how fleeting magnetic fields at the solar surface build up into the solar atmosphere.

Spintronics: X-ray microscopy unravels the nature of domain walls

A new study at BESSY II analyzes the formation of skyrmions in ferrimagnetic thin films of dysprosium and cobalt in real time and with high spatial resolution. This is an important step towards characterizing suitable materials ...
