Recently, high speed domain wall motion in a synthetic antiferromagnetic nanowire was reported. However, the experiment results included effects of spin-orbit-torques and the dominant factor has not been clarified yet. In this study, we propose a new approach for analysis of current-induced domain wall motion in a bi-layer nanowire, which is based on motion equations of domain walls with exchange and magnetostatic interactions between two domain walls.
