A possible game changer for next generation microelectronics

Posted by in categories: computing, materials

Tiny magnetic whirlpools could transform memory storage in high performance computers.

Magnets generate invisible fields that attract certain materials. A common example is refrigerator magnets. Far more important to our everyday lives, magnets also can store data in computers. Exploiting the direction of the magnetic field (say, up or down), microscopic bar magnets each can store one bit of memory as a zero or a one—the language of computers.

Scientists at the U.S. Department of Energy’s (DOE) Argonne National Laboratory want to replace the bar magnets with tiny magnetic vortices. As tiny as billionths of a meter, these vortices are called skyrmions, which form in certain . They could one day usher in a new generation of microelectronics for memory storage in .
