Functional Topological Materials
Proximity coupling of topological insulators to magnets is a promising strategy to design functional topological materials with new properties including dissipationless conducting edge states and a strong magnetoelectric effect, useful for low‐power electronics. In article number 2007795, Semonti Bhattacharyya, Michael Fuhrer, and co‐workers review the latest progress...
Inducing long‐range magnetic order in 3D topological insulators can gap the Dirac‐like metallic surface states, leading to exotic new phases such as the quantum anomalous Hall effect or the axion insulator state. These magnetic topological phases can host robust, dissipationless charge and spin currents or unique magnetoelectric behavior, which can be exploited in low‐energy electronics and spintronics...
