Abstract

Coupling a ferromagnetic insulator to a topological insulator induces a robust magnetic state at the interface, resulting from the large spin-orbit interaction and the spin-momentum locking property of Dirac fermions, and leads to an extraordinary enhancement of the magnetic ordering (Curie) temperature.
