abstract = {Reliable and energy-efficient magnetization switching by
electrically induced spin–orbit torques is of crucial
technological relevance for spintronic devices implementing
memory and logic functionality. Here we predict that the
strength of spin–orbit torques and the
Dzyaloshinskii-Moriya interaction in topologically
nontrivial magnetic insulators can exceed by far that of
conventional metals. In analogy to the quantum anomalous
Hall effect, we explain this extraordinary response in the
absence of longitudinal currents as hallmark of monopoles in
the electronic structure of systems that are interpreted
most naturally within the framework of mixed Weyl
semimetals. We thereby launch the effect of spin–orbit
torque into the field of topology and reveal its crucial
role in mediating the topological phase transitions arising
from the complex interplay between magnetization direction
and momentum-space topology. The presented concepts may be
exploited to understand and utilize magnetoelectric coupling
phenomena in insulating ferromagnets and antiferromagnets.},
