We present a microscopic electronic description of how antiskyrmions can be stabilized in a Dresselhaus spin-orbit-coupled magnetic metal. Furthermore, we show that the antiskyrmions can be tuned into Bloch skyrmions via a change in sign of the hopping integral. The results are based on the state-of-the-art hybrid Monte Carlo simulations of lattice models explicitly involving itinerant electrons. The origin of such topological textures is understood via an effective spin-only model. Our results uncover an important and useful connection between generic features of the band structure and topological spin textures of immense current interest, and present a microscopic explanation of skyrmion formation reported recently in certain magnetic Weyl semimetals.

磁性德雷塞尔豪斯金属中的反斯格明子和布洛赫斯格明子

我们对如何在德雷塞尔豪斯自旋轨道耦合磁性金属中稳定反斯格明子进行了微观电子描述。此外，我们表明可以通过跳跃积分符号的变化将反斯格明子调谐为布洛赫斯格明子。结果基于明确涉及流动电子的晶格模型的最新混合蒙特卡罗模拟。通过有效的自旋模型可以理解这种拓扑纹理的起源。我们的结果揭示了能带结构的一般特征与当前非常感兴趣的拓扑自旋纹理之间的重要且有用的联系，并对最近在某些磁性外尔半金属中报道的斯格明子形成进行了微观解释。
