| Research Abstract |
Here, we propose a programmable pinning site for racetrack memory. In racetrack memory, a notch structure is used to control domain wall propagation. However, with the notch structure, a condition of domain wall propagation is fixed at the design stage. With nanomagnets adjacent to a nanowire, the condition of domain wall propagation shows different value associated with combination of magnetization directions of the nanomagnets.
