| Summary:
Antiferromagnetic spintronics is an emerging area of quantum technologies
that leverage the coupling between spin and orbital degrees of freedom in
exotic materials. Spin-orbit interactions allow spin or angular momentum to be
injected via electrical stimuli to manipulate the spin texture of a material,
enabling the storage of information and energy. In general, the physical
process is intrinsically local: spin is carried by an electrical current,
imparted into the magnetic system, and the spin texture then rotates. The
collective excitations of complex spin textures have rarely been utilized in
this context, even though they can in principle transport spin over much longer
distances, using much lower power. In this study, we show that spin information
can be transported and stored non-locally in the material Fe$_x$NbS$_2$. We
propose that collective modes leverage the strong magnetoelastic coupling in
the system to achieve this, revealing a novel way to store spin information in
complex magnetic systems
