Abstract
We perform ab initio calculations on {\mathrm{Bi}}_{\mathrm{Se}}antisite defects in the surface of {\mathrm{Bi}}_{2}{\mathrm{Se}}_{3} finding strong low-energy defect resonances with a spontaneous ferromagnetism, fixed to an out-of-plane orientation due to an exceptionally large magnetic anisotropy energy. For antisite defects in the surface layer, we find semi-itinerant ferromagnetism and strong hybridization with the Dirac surface state,...
