摘要：

In this study, influence of interlayer exchange coupling on current-induced domain wall motion in multilayered nanowires for achieving high density bit has been analyzed by using micromagnetic simulation. As a result, the domain walls in the continuous and the granular layers move all together even if the interlayer exchange coupling is 0 erg/cm. The domain wall velocity increases with increasing interlayer exchange coupling. The total energy difference between Neel walls increases with increasing domain wall width due to the magnetostatic field generated from the granular layer.
