In magnetic semiconductors, one especially useful messenger is the exciton: a pairing of a negatively charged electron and the positively charged &#8220;hole&#8221; it leaves behind. Until now, excitons in magnetic materials have mostly been used as reporters. They could reveal how spins were arranged or how magnetic waves moved through a material. But Cornell researchers have shown that excitons can do more than observe magnetism.
