Light-induced ferromagetism (IMAGE)
Caption
A cartoon depiction of the light-induced ferromagnetism that the researchers observed in ultrathin sheets of tungsten diselenide and tungsten disulfide. Laser light, shown in yellow, excites an exciton – a bound pair of an electron (blue) and its associated positive charge, also known as a hole (red). This activity induces long range exchange interactions among other holes trapped within the moiré superlattice, orienting their spins in the same direction.
