Query: Controlling the topological sector of magnetic solitons in exfoliated
  Cr$_{1/3}$NbS$_2$ crystals   We investigate manifestations of topological order in monoaxial helimagnet
Cr$_{1/3}$NbS$_2$ by performing transport measurements on ultra-thin crystals.
Upon sweeping the magnetic field perpendicularly to the helical axis, crystals
thicker than one helix pitch (48 nm) but much thinner than the magnetic domain
size ($\sim$1 $\mu$m) are found to exhibit sharp and hysteretic resistance
jumps. We show that these phenomena originate from transitions between
topological sectors with different number of magnetic solitons. This is
confirmed by measurements on crystals thinner than 48 nm --in which the
topological sector cannot change-- that do not exhibit any jump or hysteresis.
Our results show the ability to deterministically control the topological
sector of finite-size Cr$_{1/3}$NbS$_2$ and to detect inter-sector transitions
by transport measurements.
