Energy-momentum transport through soliton in a site-dependent ferromagnet

by L. Kavitha, P. Sathishkumar and D. Gopi

Document info: Pages 25, Figures 10.

The study of energy-momentum transport phenomena between two interacting spins in a ferromagnetic system provides a good realization of physical mechanism behind it. We investigate the nonlinear spin dynamics of a site-dependent ferromagnet with inhomogeneous exchange interaction in the presence of relativistic Gilbert-damping. We demonstrate the influence of inhomogeneity and damping on the evolution of energy and current densities of the magnetization. It is found that the inhomogeneity and damping support the loss-less energy-momentum transport along the site-dependent spin chain.
