One compound with two distinct topological states

  • 439 Accesses

Two distinct topological states that are closely tied to the spin configurations of a layered compound, here MnBi2Te4, have been demonstrated. Such control of the topological state should enable new opportunities to realize quantum and spintronic devices.
