论文摘要
天空是在某些磁性有序材料中发现的磁矩的涡流状纹理。在这里，我们描述了Skyrmion的起源，并讨论了磁性材料中天空的实验实现，天际的动态特性以及Skyrmions与电子的潜在有用相互作用。我们的讨论基于田地的物理学，并使我们能够谈到田间理论和拓扑的概念，这些概念说明了如何将天空理解为有序领域中缺陷家族的一部分，并暗示了等待我们发现的其他拓扑对象。
Skyrmions are vortex-like textures of magnetic moments found in some magnetically ordered materials. Here we describe the origin of the skyrmion and discuss the experimental realization of skyrmions in magnetic materials, the dynamic properties of the skyrmion and the potentially useful interaction of skyrmions with electrons. Our discussion is based on the physics of fields and allows us to touch on notions from field theory and topology that illustrate how skyrmions can be understood as part of a family of defects in an ordered field, and hint at other topological objects that await our discovery.
