spelling Topological character and magnetism of the Dirac state in Mn-Doped Bi2Te3Henk, J.Flieger, M.Maznichenko, I. V.Mertig, I.Ernst, ArthurEremeev, Sergey V.Chulkov, Eugene V.Trabajo presentado como póster al CECAM Workshop on "Topological Materials" celebrado en Bremen (Alemania) del 13 al 17 de Agosto de 2012.First-principles and model calculations show that the Dirac surface state of the topological insulator Bi 2Te 3 survives upon moderate Mn doping of the surface layers but can lose its topological character as a function of magnetization direction. The dispersion depends considerably on the direction of the Mn magnetization: for perpendicular magnetization, a gap of 16 meV opens up at the Dirac point; for in-plane magnetization, a tiny gap can be opened or closed in dependence on the magnetization azimuth. The ground state is ferromagnetic, with a critical temperature of 12 K. The results provide a path towards a magnetic control of the topological character of the Dirac surface state and its consequences to spin-dependent transport properties. © 2012 American Physical Society.Peer ReviewedAmerican Physical Society2014201420122014info:eu-repo/semantics/articlehttp://purl.org/coar/resource_type/c_6501Publisher's versioninfo:eu-repo/semantics/publishedVersionhttp://hdl.handle.net/10261/102082reponame:DIGITAL.CSIC.
