abstract = {Using the Kubo linear-response formalism we derive
expressions to calculate the electronic contribution to the
heat current generated by magnetization dynamics in
ferromagnetic metals with broken inversion symmetry and
spin–orbit interaction (SOI). The effect of producing heat
currents by magnetization dynamics constitutes the Onsager
reciprocal of the thermal spin–orbit torque (TSOT), i.e.
the generation of torques on the magnetization due to
temperature gradients. We find that the energy current
driven by magnetization dynamics contains a contribution
from the Dzyaloshinskii–Moriya interaction (DMI), which
needs to be subtracted from the Kubo linear response of the
energy current in order to extract the heat current. We show
that the expressions of the DMI coefficient can be derived
elegantly from the DMI energy current. Guided by formal
analogies between the Berry phase theory of DMI on the one
hand and the modern theory of orbital magnetization on the
other hand we are led to an interpretation of the latter in
terms of energy currents as well. Based on ab initio
calculations we investigate the electronic contribution to
the heat current driven by magnetization dynamics in Mn/W(0
0 1) magnetic bilayers. We predict that fast domain walls
drive strong heat currents.},
