We study the velocity and energy consumption of current induced magnetic domain wall (DW) movement, which is a new paradigm in spintronics devices such as a next generation MRAM and race track memory, by LLG (Landau-Lifshitz- Gilbert) micromagnetic simulation. It is found that DW velocity is almost the same in current in magnetic thin film plane(CIP) and current perpendicular to plane (CPP-Perp.). On the other hand, the energy consumption is much lower in CPP-Perp. than CIP. These results show that the CPP-Perp. structure has potential solutions for high speed and low energy consumption applications.
