附注	we study theoretically the rkky interaction between magnetic impurities on the surface of three-dimensional topological insulators, mediated by the helical dirac electrons. exact analytical expression shows that the rkky interaction consists of the heisenberg-like, ising-like, and dzyaloshinskii-moriya (dm)-like terms. it provides us a new way to control surface magnetism electrically. the gap opened by doped magnetic ions can lead to a short-range bloembergen-rowland interaction. the competition among the heisenberg, ising, and dm terms leads to rich spin configurations and an anomalous hall effect on different lattices.
