Abstract

van der Waals magnetic materials open up exciting possibilities to investigate fundamental spin properties in low-dimensional systems and to build compact functional spintronic structures. This review focuses on the recent progress in two-dimensional(2D) magnets that explore beyond the homogenous magnetically-ordered state, including magnons (spin waves), magnetic skyrmions, and complex magnetic domains. Properties of these spin and topology excitations in 2D magnets provide insights into spin-orbit interactions and other forms of coupling between electrons, phonons, and spin-dependent excitations. Such spin-based quasiparticles can also serve as information carriers for next-generation high-speed computing elements. We will first lay out the general theoretical basis of dynamical responses in magnetic systems, followed by detailed descriptions of experimental progress in magnons and spin textures (including magnetic domains and skyrmions). Discussion on the experimental techniques and future perspectives are also included.

二维磁体中的自旋激发和动力学：磁振子和磁天子的概述

范德华磁性材料为研究低维系统的基本自旋特性和构建紧凑的功能自旋电子结构开辟了令人兴奋的可能性。本文综述了二维（2D）磁体的最新进展，包括磁振子（自旋波）、磁skyrmions和复杂磁畴。二维磁体中这些自旋和拓扑激发的性质为电子、声子和自旋相关激发之间的自旋轨道相互作用和其他形式的耦合提供了见解。这种基于自旋的准粒子也可以作为下一代高速计算元件的信息载体。我们将首先阐述磁系统中动态响应的一般理论基础，然后详细描述磁振子和自旋织构（包括磁畴和skyrmions）的实验进展。讨论了实验技术和未来的展望。
