Zusammenfassung:	To provide magnetic thin wire media that are driven by a low current and can detect a magneto-optical image, and a magnetic domain wall drive type spatial light modulator.SOLUTION: Magnetic thin wire media 10 include: a magnetic thin wire 11; an insulation thin film 13 formed on the magnetic thin wire 11; and a metal thin film 15 formed on the insulation thin film 13. The thickness of the insulation thin film 13 and the thickness of the metal thin film 15 are smaller than a penetration length of incident light. The material of the insulation thin film 13 is a topological insulator. The material of the metal thin film 15 is a metal material that reduces a degree of surface roughness of the insulation thin film 13, which is ruthenium.SELECTED DRAWING: Figure 4 【課題】低電流で駆動し、かつ、磁気光学像を検出できる磁性細線媒体および磁壁駆動型空間光変調器を提供する。【解決手段】磁性細線媒体１０は、磁性細線１１と、磁性細線１１の上に形成された絶縁薄膜１３と、絶縁薄膜１３の上に形成された金属薄膜１５と、を備え、絶縁薄膜１３の厚さおよび金属薄膜１５の厚さは入射光の侵入長より小さく、絶縁薄膜１３の材料は、トポロジカル絶縁体であり、金属薄膜１５の材料は、絶縁薄膜１３の表面粗さの程度を緩和する金属材料であって、ルテニウムである。【選択図】図４
