Chemical bonding principles in magnetic topological quantum materials

Topological materials have received extensive attention in condensed matter and solid-state chemistry research since the emergence of graphene as a Dirac semimetal given strong spin-orbit coupling. With incorporating magnetism into topological materials, new quantum phenomena can be realized with an interplay between the magnetism and topological states, thereby providing a unique approach to various exotic electronic states. In the review, we will present the connections among chemical charge balance arguments with atoms in the real space with the electronic bands in the k-space in the topological materials. We focus on design of novel magnetic topological materials from chemistry perspectives. Technically, we emphasize the utilization of neutron scattering to understand magnetic topological materials. The review ends up with introducing the high pressure to tune atomic distances and the electronic bands to induce new quantum topological states.
