Outline of Final Research Achievements

Race track memory recently attracts attention as one of the future recording devices with ultra-high capacity, in which magnetic domain wall displacement is employed for information recording. Quite simple and easy method of domain wall introduction was proposed and successfully demonstrated experimentally. The domain wall introduction was enabled by an exchange coupled composite structure of hard and soft magnetic layers partially arranged in the magnetic wire. The domain wall introduction and the displacements were successfully detected through a polar Kerr effect detection.
A potential problems of overshoot phenomenon for domain wall displacements due to change in the domain wall structures was numerically found to be solved by setting aspect ratio of wire width and the thickness to balance the domain wall energies for Neel and Bloch walls. A micromagnetic simulator has been developed for designing 3 dimensional spin devices involving multi-dimensional current distribution.
