Soliton dynamics in two ferromagnetic chains coupled through interactions between opposite and diagonal spins

Abstract

Abstract A system of two anisotropic ferromagnetic chains coupled through the interactions between both opposite and diagonal spins is investigated. For the easy-axis on-site anisotropy the system possess soliton solutions. We studied the influence of the coupling constants on the soliton parameters. We obtained that the coupling between opposite spins does not change the soliton parameters while the coupling between diagonal spins has influence on the form and the velocity of the soliton. Further we considered the propagation of a soliton excitation launched in one of the chains and obtained the condition for its perfect switching.
