abstract = {Using the linear response formalism, we compute from first
principles the spin-orbit torque (SOT) in a system of two
layers of L10−FePt(001) deposited on an fcc Pt(001)
substrate of varying thickness. We find that at room
temperature the values of the SOTs that are even and odd
with respect to magnetization generally lie in the range of
values measured and computed for Co/Pt bilayers. We also
observe that the even SOT is much more robust with respect
to changing the number of layers in the substrate, and as a
function of energy it follows the general trend of the even
SOT exerted by the spin Hall current in fcc Pt. The odd
torque, on the other hand, is strongly affected by
modification of the electronic structure for a specific
energy window in the limit of very thin films. Moreover,
taking the system at hand as an example, we compute the
values of the thermal spin-orbit torque (TSOT). We predict
that the gradients of temperature which can be
experimentally created in this type of system will cause a
detectable torque on the magnetization. We also underline
the correlation between the even TSOT and the spin Nernst
effect, thus motivating a more intensive experimental effort
aimed at an observation of both phenomena.},
