abstract = {The control of domain walls is central to nearly all
magnetic technologies, particularly for information storage
and spintronics. Creative attempts to increase storage
density need to overcome volatility due to thermal
fluctuations of nanoscopic domains and heating limitations.
Topological defects, such as solitons, skyrmions, and
merons, may be much less susceptible to fluctuations, owing
to topological constraints, while also being controllable
with low current densities. Here, we present the first
evidence for soliton/soliton and soliton/antisoliton domain
walls in the hexagonal chiral magnet Mn1/3NbS2 that respond
asymmetrically to magnetic fields and exhibit
pair-annihilation. This is important because it suggests the
possibility of controlling the occurrence of soliton pairs
and the use of small fields or small currents to control
nanoscopic magnetic domains. Specifically, our data suggest
that either soliton/soliton or soliton/antisoliton pairs can
be stabilized by tuning the balance between intrinsic
exchange interactions and long-range magnetostatics in
restricted geometries.},
