Query: Dynamics of chiral solitons driven by polarized currents in monoaxial
  helimagnets   Chiral solitons are one dimensional localized magnetic structures that are
metastable in some ferromagnetic systems with Dzyaloshinskii-Moriya
interactions and/or uniaxial magnetic anisotropy. Though topological textures
in general provide a very interesting playground for new spintronics phenomena,
how to properly create and control single chiral solitons is still unclear. We
show here that chiral solitons in monoaxial helimagnets, characterized by a
uniaxial Dzyaloshinskii-Moriya interaction, can be stabilized with external
magnetic fields. Once created, the soliton moves steadily in response to a
polarized electric current, provided the induced spin-transfer torque has a
dissipative (nonadiabatic) component. The structure of the soliton depends on
the applied current density in such a way that steady motion exists only if the
applied current density is lower than a critical value, beyond which the
soliton is no longer stable.
