      abstract     = {We investigate the spin-orbit torque exerted on the
                      magnetic moments of the transition-metal impurities Cr, Mn,
                      Fe, and Co, embedded in the surface of the topological
                      insulator Bi2Te3, in response to an electric field and a
                      consequent electrical current flow in the surface. The
                      multiple scattering problem of electrons off impurity atoms
                      is solved by first-principles calculations within the
                      full-potential relativistic Korringa-Kohn-Rostoker (KKR)
                      Green function method, while the spin-orbit torque
                      calculations are carried out by combining the KKR method
                      with the semiclassical Boltzmann transport equation. We
                      analyze the correlation of the spin-orbit torque to the spin
                      accumulation and spin flux in the impurities and unveil the
                      effect of resonant scattering. In addition, we relate the
                      torque to the resistivity and Joule heat production. We
                      predict that the Mn/Bi2Te3 is optimal among the studied
                      systems.},
