"computers that need < 1/M of energy required to switch single bit... Mn-doped GeTe sensitive to both magnetic and electric fields... small, constantly fluctuating (AC) electrical current, followed by a tiny current nudge at just the right moment, forcing one spin to change its orientation in effect creates a wave through the sample and cause the other magnetic moments to also switch... more efficient, compact, energy-saving... enhancing switching magnetization direction efficiency 6 orders magnitude"
