摘要

磁性斯格明子是一种具有拓扑保护的纳米尺度磁畴结构,其小尺寸、易被电流驱动、低能耗等优点使其成为磁信息存储和自旋电子学器件的核心候选材料,近年来备受人们关注。文章将着重介绍:(1)磁性斯格明子产生的机理;(2)探测磁性斯格明子的方法或者手段;(3)近期国际上研究的几种磁性斯格明子材料;(4)磁性斯格明子诱导产生新颖的霍尔效应——拓扑霍尔效应;(5)结论与展望。

Abstract

Magnetic skyrmions are topologically protected vortex-like nanometric spin textures that have recently received growingly attention for their potential applications in future high-performance spintronic devices. In this article we discuss the following topics, i.e. (1) Various mechanisms of generating skyrmions in magnetic systems; (2) The observed of the skyrmions; (3) Skyrmions in some typical material environments; (4) Unique topological phenomena-Topological Hall Effect (THE) ; (5) Summary and perspective.
