Topology-driven magnetic quantum phase transition in topological insulators

Topological insulator （TI）, in which strong spin-orbital coupling induces topologically nontrivial band structure, is one of the most important frontiers in condensed matter physics. The interplay between to- pology and magnetism in TIs has attracted much research interests. Most previous studies focus on the effect of magnetism on the topological surface states, but little is known about how the magnetic ordering is affected by the topological property.
