Effect of Dilute Magnetism in a Topological Insulator

Three-dimensional (3D) topological insulator (TI) has emerged as a unique state of quantum matter and generated enormous interests in condensed matter physics.The surfaces of a 3D TI consist of a massless Dirac cone, which is characterized by the Z2 topological invariant.Introduction of magnetism on the surface of a TI is essential to realize the q
