Researchers at MIT have devised a new approach using spintronics to control magnetism in a microchip. Their method could pave the way for new designs in memory, computing, and sensing devices that consume significantly less power than existing devices.A team at the MIT Materials Research Laboratory-working with researchers at Brookhaven National Laboratory-has shown that by applying a small voltage, they can control the magnetic properties of a thin-film material. The changes in magnetic orientation remain in their new state without the need for any ongoing power, which is unlike today's standard memory chips and could help overcome some design limitations, researchers found.
