    摘要: A data storage device using magnetic domain wall motion may include a first magnetic layer having a plurality of magnetic domains. A second magnetic layer may be connected to the first magnetic layer, and a connection layer may be disposed between the first and second magnetic layers. A resistive magnetic layer may be disposed between each of the first and second magnetic layers and the connection layer. Accordingly, when current is supplied to the data storage device to move a magnetic domain wall, the leakage of current in a connection between the magnetic layers may be reduced or prevented, thus conserving power.
