"more energy efficient than ones made of silicon, not subject to size and speed constraints... passed current through 5° Kelvin manganese bismuth telluride antiferromagnets, unique voltage was measured, depending on whether positive or negative determines if coded as 1 or 0... change between 1 and 0 states 100X faster... not disturbed in presence of other magnets, and more memory capacity... energy from Wi-Fi and mobile signals could cause antiferromagnets to produce electricity powering portable electronic devices"
