| Outline of Final Research Achievements |
Recently a storage system, which uses a magnetic domain wall as an information carrier was proposed, and the domain wall have been studied intensively. Because the domain wall motion velocity is related to the operation speed of the storage system, it is required to obtain the conditions for fast domain wall motion, and to investigate the domain wall motion mechanism. In this research, the effect of the Dzyaroshinskii-Moriya interaction on the domain wall motion induced by a spin current, a magnetic field, and an electric field were investigated by computer simulation, and obtained the conditions for fast domain wall motion, and revealed the domain wall motion mechanism.
