摘要
磁性斯格明子是一种实空间拓扑准粒子,它展现出丰富、新奇的物理性质,为自旋电子学的研究提供了新的方向。另一方面,由于其具有尺寸小、稳定性高、易操控等特性,在未来的存储器件中也有潜在应用价值。本文简单介绍了在国家重点研发计划量子调控与量子信息重点专项(2017YFA0303200)资助下,对基于Dzyaloshinsky-Moriya相互作用和人工的两种磁性斯格明子进行的系统研究。
Magnetic skyrmion is a topological quasiparticle in the real space. Due to the observed unconventional phenomena, magnetic skyrmion has become a hot topic in spintronics community. In addition, magnetic skyrmions are also promising candidates for future information technology due to their small size and to the small current densities needed to displace them. In this article, we review our recent progress on the magnetic skyrmion with and without Dzyaloshinsky-Moriya interaction under the support of the National Key R&D Program of China (Grant 2017YFA0303200).
