A research team from Cornell University in the United States has made a groundbreaking discovery: by applying voltage to a four-layer graphene material, its relative interlayer arrangement can be modified. This modification allows the material to toggle between non-magnetic and magnetic states. Impressively, the magnetic state remains stable even after the voltage is withdrawn. This finding opens up a novel avenue for manipulating the quantum properties of two-dimensional materials and holds promise for advancing research into reconfigurable quantum materials and innovative non-volatile memory devices.
