Tiny magnets do big work
by Guanhua (Tibbers) Hao, Peter Dowben

Think of the hard disk in your computer. Information is stored there in the form of magnetic "bits." But do you know how small a magnet can be? Some molecules make magnetic magic, and these special molecules may give rise to the ultrafast, high precision, low power devices of the future.

Magnets with a twist
by Aldo Raeliarijaona, Alexey Kovalev

In most magnetic materials, the magnetic moments of individual atoms are aligned parallel to one another and point in the same direction. In special structures called skyrmions and antiskyrmions, however, they are arranged in a spiraling pattern. Their stability and compact size makes skyrmions and antiskyrmions especially useful for encoding lots of data in a small space. But a few questions need to be answered before skyrmion-based technology can be used in your iPhone or other memory devices. First, why do these magnetic structures form in some materials and not others? How can we design a system where they will form? And how can we generate these structures on demand? Click to find out!
