From nonmagnetic to magnetic: A 2D semiconductor with electrically tunable magnetism

What happened

Researchers from the National University of Singapore (NUS), in collaboration with scientists from institutions in Switzerland, the Czech Republic and Germany, have demonstrated a way to introduce magnetism into an otherwise nonmagnetic two-dimensional (2D) semiconductor and subsequently control its magnetic properties using an electrical voltage. The findings, published in Science Advances, establish a new platform for investigating electrically controllable magnetism in atomically thin materials, with potential implications for future spintronic technologies.
