Abstract
In this study we report on a simulation study of hopping-based spin transport. Our major focus is on the spin diffusion length and its dependence on the relative strengths of spin–orbit coupling, hyperfine interactions, and exchange coupling. The general trends observed in the simulated diffusion length are found to agree with analytical scaling relations proposed in the literature. • A combined Monte Carlo/Molecular Dynamics study of hopping spin transport is performed. • The dependence of the spin diffusion length on the carrier concentration is nontrivial.
