Blowing bubbles: the birth of a skyrmion

Researchers at UCLA and the U.S. Department of Energy’s Argonne National Laboratory announced today a new method for creating magnetic skyrmion bubbles at room temperature. The bubbles, a physics phenomenon thought to be an option for more energy-efficient and compact electronics, can be created with simple equipment and common materials.

Skyrmions, discovered just a few years ago, are tiny islands of magnetism that form in certain materials. If you wrapped one up into a sphere, its magnetic fields would point away in all different directions—so they stay in neat little packages and don’t unravel easily.
