abstract = {Using high-throughput automation of ab initio impurity
embedding simulations, we create a database of 3d and 4d
transition metal defects embedded into the prototypical
topological insulators (TIs) Bi 2 Te 3 andBi 2 Se 3 . We
simulate both single impurities as well as impurity dimers
at different impurity-impurity distances inside the
topological insulator matrix. We extract changes to magnetic
moments, analyze the polarizability ofnonmagnetic impurity
atoms via nearby magnetic impurity atoms and calculate the
exchange coupling constants for a Heisenberg Hamiltonian. We
uncover chemical trends in the exchange coupling constants
and discussthe impurities’ abilities with respect to
magnetic order in the fields of quantum anomalous Hall
insulators and topological quantum computing. In particular,
we confirm that co-doping of different magnetic dopants is
aviable strategy to engineer the magnetic ground state in
magnetic TIs.},
