Abstract:
1. A current injection-type magnetic domain wall-motion device comprising: a first magnetic film directly adjacent to a third magnetic film and a second magnetic film directly adjacent to the third magnetic film, the second magnetic film having a magnetization direction antiparallel to that of the first magnetic film, a first microjunction interface between the first and the third magnetic films, and a second microjunction interface between the third and the second magnetic films, wherein the magnetization direction of the third magnetic film is controlled by a current that is applied to pass through the first and second microjunction interfaces, wherein a magnetic domain wall present between the first and second magnetic film is moved within the third magnetic film in the same direction as a flow of the current or in the direction opposite to the flow of the current by direct interaction between the magnetic domain wall and the flow of the current.
