摘要
磁斯格明子因具有拓扑稳定、移动速度快、尺寸小、驱动电流密度低等优异性质引起了人们的广泛关注。它被视作未来超高密度磁存储和逻辑功能器件的理想信息载体。基于磁斯格明子的自旋电子学器件具有非易失、高读写速度、高存储密度以及低功耗的优势,从而能满足人们对高性能器件的要求。此外,拓扑性与磁性的结合使得磁斯格明子成为研究拓扑磁性物理的良好平台。文章简要介绍了磁斯格明子的发展概况及其拓扑物理性质,并着重讨论薄膜异质结及二维材料中磁斯格明子的研究进展,为今后进一步探索磁斯格明子相关研究领域抛砖引玉。
Magnetic skyrmions,nanomagnetic structures with high topological proper‐ties,high speed,small size,and low motion-driving current density,have received wide attention.They may be expected to function as ideal information carriers for ultra-high density magnetic storage and logic function devices in the future.These magnetic skyrmion-based devices have the advantages of non-volatile high-density storage,high read/write speed,and low-energy consumption.Moreover,the combination of topology and magnetism renders them a good platform for the study of topological magnetism.Here,we briefly describe the history and topological physics of magnetic skyrmions,then discuss their use in magnetic thin films and two-dimensional magnetic materials.We hope that this review can pave an avenue for further studies of skyrmion-based spintronics.
