Magnetism-induced massive Dirac spectra and topological defects in the surface state of Cr-doped Bi2Se3-bilayer topological insulators

Proximity-induced magnetic effects on the surface Dirac spectra of topological insulators are investigated by scanning tunneling spectroscopic studies of bilayer structures consisting of undoped Bi _2 Se _3 thin films on top of Cr-doped Bi _2 Se _3 layers. For thickness of the top Bi _2 Se _3 layer...
