Query: Extended exchange interactions stabilize long-period magnetic structures
  in Cr$_{1/3}$NbS$_2$   The topologically-protected, chiral soliton lattice is a unique state of
matter offering intriguing functionality and it may serve as a robust platform
for storing and transporting information in future spintronics devices. While
the monoaxial chiral magnet Cr$_{1/3}$NbS$_2$ is known to host this exotic
state in an applied magnetic field, its detailed microscopic origin has
remained a matter of debate. Here we work towards addressing this open question
by measuring the spin wave spectrum of Cr$_{1/3}$NbS$_2$ over the entire
Brillouin zone with inelastic neutron scattering. The well-defined spin wave
modes allow us to determine the values of several microscopic interactions for
this system. The experimental data is well-explained by a Heisenberg
Hamiltonian with exchange constants up to third nearest neighbor and an easy
plane magnetocrystalline anisotropy term. Our work shows that both the second
and third nearest neighbor exchange interactions contribute to the formation of
the helimagnetic and chiral soliton lattice states in this robust
three-dimensional magnet.
