Abstract
The spin dynamics in antiferromagnets with atomic dislocations and dislocation-induced spin disclinations has been discussed. It is shown how the usual sigma-model equation can be used to describe it. The dynamical states with the spatially inhomogeneous spin precession are studied. It is demonstrated that such an internal dynamics of the spin disclinations and the related domain walls can serve as a basis for creating a spin-Hall nanogenerator pumped with a spin current and characterized by a low excitation threshold.
