abstract = {We investigate from first principles the fieldlike
spin-orbit torques (SOTs) in a Ag2Bi-terminated Ag(111) film
grown on ferromagnetic Fe(110). We find that a large part of
the SOT arises from the spin-orbit interaction (SOI) in the
Ag2Bi layer far away from the Fe layers. These results
clearly hint at a long-range spin transfer in the direction
perpendicular to the film that does not originate in the
spin Hall effect. In order to bring evidence of the nonlocal
character of the computed SOT, we show that the torque
acting on the Fe layers can be engineered by the
introduction of Bi vacancies in the Ag2Bi layer. Overall, we
find a drastic dependence of the SOT on the disorder type,
which we explain by a complex interplay of different
contributions to the SOT in the Brillouin zone},
