Researchers discover new material for optically-controlled magnetic memory

Researchers at the University of Chicago Pritzker School of Molecular Engineering (PME) have made unexpected progress toward developing a new optical memory that can quickly and energy-efficiently store and access computational data. While studying a complex material composed of manganese, bismuth and tellurium (MnBi2Te4), the researchers realized that the material's magnetic properties changed quickly and easily in response to light. This means that a laser could be used to encode information w...
