When order gives way to chaos—the turbulent birth of magnetic nanovortices

Phys · · 492 words · By Max Born Institute; Short Pulse Spectroscopy

Researchers from several German institutes used X-ray microscopy to observe the effects of short current pulses on skyrmions. They discovered that above a certain threshold, skyrmions undergo a brief period of chaotic motion and 'shedding' before returning to a stable state, potentially enabling new computing concepts.
