DESCRIPTION
Researchers developed graphene discs that generate magnetic fields 10,000x Earth's - switchable in picoseconds. By stirring electrons with light, discs produce swirling plasmons acting as nanomagnets toggled in trillionths of a second, enabling dynamic control from quantum dots to magnetocaloric materials.
