磁性細線媒体の製造方法

Abstract

To provide a magnetic thin wire medium which can be driven with a low current, a magnetic wall drive type memory, a magnetic wall drive type spatial optical modulator, and a manufacturing method for the magnetic thin wire medium which can be driven with a low current.SOLUTION: In a magnetic wall drive type memory, a magnetic thin wire medium 10 comprises a plurality of magnetic thin wires 11, a barrier layer 12 formed of MgO on the respective magnetic thin wires 11, and a topological insulator thin film 13 formed on the barrier layer 12. A method of manufacturing the magnetic thin wire medium includes the steps of: forming a barrier layer on a magnetic body; forming a topological insulator thin film on the barrier layer; and processing a laminate consisting of the magnetic body, the barrier layer and the topological insulator thin film into a plurality of thin wires which are parallel in plan view.SELECTED DRAWING: Figure 3
