Magnetic Fields at the Crossroads

Almost all information that exists in contemporary society is recorded in magnetic media, like hard drive disks. Researchers are studying the motion of vortex domain walls -- local regions of charge that collectively store information via their configuration -- driven by magnetic fields in ferromagnetic nanowires, which are configured in a straight line with an asymmetric Y-like branch. They discuss their work in this week's Journal of Applied Physics.
