Realization of an intrinsic ferromagnetic topological state in MnBi <sub>8</sub> Te <sub>13</sub>
The interplay between topology and magnetism is essential for realizing novel topological states including the axion insulator, the magnetic Weyl semimetal, etc. An intrinsically ferromagnetic topological material with only the topological bands at the charge neutrality energy has so far remained elusive. By rationally designing the natural heterostructure consisting of …
