Abstract: The current-driven domain motion of a multi-wall in a magnetic nanowire with perpendicular magnetic anisotropy was analyzed in this study by using micromagnetic simulation. As a result, we found that there were two modes in the multi-wall motion, and the motion was determined by the applied current density and non-adiabatic spin torque parameters; this was similar to single-wall motion. The x-component of magnetization in the domain wall exhibited different behavior according to the current density. The bit length was extended for a low current density and the bit length was varied for a high current density due to interaction between the magnetic domain walls.
