Query: Large interfacial spin-orbit torques in layered antiferromagnetic
  insulator NiPS$_3$/ferromagnet bilayers   Finding efficient ways of manipulating magnetic bits is one of the core goals
in spintronic research. Electrically-generated spin-orbit torques (SOTs) are
good candidates for this and the search for materials capable of generating
highly-efficient SOTs has gained a lot of traction in the recent years. While
antiferromagnet/ferromagnet bilayer structures have been employed extensively
for passive applications, e.g. by using exchange bias fields, their active
properties are not yet widely employed. Here we show the presence of large
interfacial SOTs in bilayer of a ferromagnet and the two-dimensional layered
antiferromagnetic insulator NiPS$_3$. We observe a large in-plane damping-like
interfacial torque, showing a torque conductivity of $\sigma_\mathrm{DL}
\approx 1 \times 10^{5} \mathrm{(\frac{\hbar}{2e}) /(\Omega m)}$ even at room
temperature, comparable to the best devices reported in the literature for
standard heavy-metal-based and topological insulators-based devices.
Additionally, our devices also show an out-of-plane field-like torque arising
from the NiPS$_3$/ferromagnet interface, further indicating the presence of an
interfacial spin-orbit coupling in our structures. Temperature-dependent
measurements reveal an increase of the SOTs with a decreasing temperature below
the N\'eel temperature of NiPS$_3$ ($T_N \approx 170 \mathrm{K}$), pointing to
a possible effect of the magnetic ordering on our measured SOTs. Our findings
show the potential of antiferromagnetic insulators and two-dimensional
materials for future spintronic applications.
