We consider the spin-current-driven dynamics of a magnetic nanostructure in a conductive magnetic wire under a heat gradient in an open-circuit, spin-Seebeck-effect geometry. It is shown that the spin-current scattering results in a spin-current torque acting on the nanostructure and leading to precession and displacement. The scattering leads also to a redistribution of the spin electrochemical potential along the wire, resulting in a break of the polarity-reversal symmetry of the inverse spin Hall effect voltage with respect to the heat-gradient inversion.
