Abstract

We discuss the structure of the domain walls (DWs) in ferromagnetic nanostripes formed of cubic-anisotropy materials. Within certain approximations, such stationary textures are described by soliton solutions to the sine-Gordon equation in 2-D that is obtained with a constraint on the Landau-Lifshitz equation. Preferable stable and metastable types of the DWs (transverse DWs, vortex DWs, and others) are established with dependence on the stripe width and thickness using the micromagnetic simulations for a set of the so-called spintronic materials, which are of the current interest with regard to controlling the DW state. The simulated DW textures are classified on the basis of the stationary multisoliton states of the sine-Gordon model in 2-D.
