DATA STORAGE DEVICE USING MAGNETIC DOMAIN WALL MOTION

摘要

A data storage device using magnetic domain wall motion is provided to prevent current leakage at connections between magnetic layers when current is applied to move a magnetic domain wall, thereby suppressing reduction in current density at the connection between magnetic layers. A data storage device using magnetic domain wall motion comprises a first magnetic layer(21a), a second magnetic layer(21b), a connection layer(23), and a resistive magnetic layer(201,202). The first magnetic layer comprises a plurality of magnetic domains. The second magnetic layer is formed on the first magnetic layer. The connection layer is formed between the first and second magnetic layers. The resistive layer is formed between the first and second magnetic layers, and the connection layer.
