Scientists from National Taiwan University discovered a rare collaboration between electricity and magnetism in the 2D ferromagnet Fe₅GeTe₂ at room temperature.
The material's unique iron atoms allow electric and magnetic effects to interact closely, creating synchronized quantum effects like charge density waves, the Kondo effect, and ferromagnetism in a repeating pattern.
Using scanning tunneling microscopy, researchers observed the synchronized quantum states forming a √3 × √3 superlattice, a phenomenon predicted but never directly observed before.
The discovery challenges the belief that electrical and magnetic properties must compete, offering new possibilities for quantum technology advancement with smaller, faster, and more powerful devices.
