| Outline of Final Research Achievements |
In the current driven domain wall motion on the magnetic wire, Rashba effect, spin Hall effect, Dzyaloshinskii Moriya effect are very important to
control the domain wall. To create a reflux type magnetic wires, it is necessary to make a symmetrical structure and an asymmetric structure in the magnetic nanowire. When Pt and SiO2 layers were used for the asymmetric structure, the domain wall motion at conecting part between the symmetric and the asymmetric wire of the reflux type magnetic wires did not move smoothly. It is considered due to the difference in level of the switching part. To avoid the problem, 2nm Pt layer and 5nm Pt layers were used for the asymmetric part. In this case, domain wall can move smoothly at the swiching part of the new type reflux type magnetic wires. In the future, it is necessary to confirm the operation stability of the current driven domain wall motion.
